Black eyed susan vine

Black- Eyed Susan vines are not to be confused with the bushy Black-Eyed Susan wildflower (Rudbeckia Hirtathat) that is native to the U.S. The Black-Eyed Susan vine (Thunbergia Alata) is a tropical plant that originally came from parts of Africa, Asia, and Madagascar. The only real similarity between the two is that both bear flowers with dark centers surrounded by bright yellow or orange petals.

This climber is evergreen only in zones 10 and above, where it can grow to be 20 feet; in a colder climate it is grown as an annual and reaches about eight feet. The dark green leaves are arrow-shaped and get up to 3” in size, and the vines bloom profusely from the early summer through the fall with five-petaled flowers in the familiar yellow and orange, but are also available in salmon, rose and apricot.

Black-Eyed Susan vines can be started from seed purchased from our store or from seeds you collect and save from growing the vine yourself. Simply collect the dried seed pods from the vine after it has bloomed and store them in a plastic bag. They will remain viable for at least two years if kept dry and not frozen.

Propagation

  • Seeds should be sown directly into garden soil in the spring after all danger of frost has passed, or indoors 7-8 weeks before the last frost. Germination takes approximately 10-15 days with the ground temperature or growing medium at 70-75 degrees.
  • Seeds of this plant germinate slowly, so don’t expect to see any sprouts for two to three weeks after planting. Some gardeners believe that soaking the seeds overnight before planting speeds up the germination process by softening the seeds’ hard shells.
  • Another method of propagation is to take a stem cutting from your vine and put it in water until it starts to grow its own roots, then plant the cutting directly into the ground or container.
  • Layering is another way of propagating the vines that work especially well in warmer climates where the plant is perennial. Take part of the vine that is already low to the ground and bend it so the last six to eight inches can be covered with earth without removing it from the plant. Stake it down and keep it watered, and in a few weeks, roots will have formed. You can then cut it off the mother plant and it will become a vine on its own.
  • In warm climates, Black-Eyed Susan vines often propagate on their own, with new plants growing from seeds the plant dropped on the ground.

Soil

Thunbergias require rich, well-drained soil, so if they are sown into the ground directly, add a good amount of compost to the soil at planting time. If you prefer to grow your Susans in planters or hanging baskets, use a high-quality potting soil.

Sun

Black-Eyed Susan vines grow best with a combination of sun and light shade, and in the hotter regions they require shade during the afternoon. They will continue to bloom as long as they get several hours of sun daily and the temperature remains above 60 degrees.

Water

Black-Eyed Susans are tropical plants and are not drought-tolerant. A layer of mulch will greatly help the soil retain its moisture. The soil in baskets or containers must not be allowed to dry out completely. Water regularly and thoroughly.

Feeding

During its blooming season, use a half-strength solution of bloom-enhancing fertilizer every two to three weeks.

Pruning

Once established, this vine can be trimmed and shaped (lightly) during the growing season, but any heavier pruning should be done in the early spring before the new growth starts.

Vine Support

Always have the climbing structure (fence, trellis, pole) in place before you plant, since you don’t want to disturb the seedlings by having to dig and construct by them.

Pests

Black-Eyed Susan vines do not have many problems from disease or insects. They can become infested with whiteflies or spider mites, but these can generally be treated with an insecticidal soap rather than chemical pesticides.

The Black-Eyed Susan vine is a rapidly growing climber or ground cover that will ramble and twine up trellises and through fences, producing masses of colorful blooms and rich green foliage. They produce bright, cheery garden color spots that will delight the gardener and attract birds, bees and butterflies.

Thunbergia, Black-Eyed Susan Vine, Clock Vine

Thunbergia, also known as black-eyed Susan vine or clock vine, is a quick-growing vine boasting many open-faced flowers, usually with dark centers (hence the name “black-eyed Susan”). Where not struck down by frost it is a perennial, but most climates of the United States grow it as a beautiful annual. The name Thunbergia honors a Swedish botanist named Karl Pehr Thunberg.

: Black-eyed Susan vine can grow 6 to 8 feet tall in a season and has rough, hairy leaves. The blooms have 5 distinct petals and are symmetrical. Flower color can be white, yellow, orange, or cream. Most of them have dark centers.

: Generally, it grows best in full sun. It needs average, well-drained soil. Plant seedlings 3 inches away from supports. Space plants 5 to 8 inches apart. Pinch the tips to encourage branching. Since thunbergias climb by twining, netting or strings make good trellising materials. They will need a trellis to climb large posts or solid fencing.

: By seed or by cuttings. Sow seeds outdoors after the last frost or start seedlings indoors 6 to 8 weeks before outdoor planting. Seeds germinate in 10 to 15 days at 70 to 75 degrees Fahrenheit. Cuttings root easily in a commercial soil mix.

: Thunbergias can be used to cover posts, porches, arbors, pergolas, or fences. They also make good container plants. Plants in containers will also bloom over winter in sunny windows.

Thunbergia, black-eyed Susan vine, clock vine related species: Thunbergia gibsonii has somewhat larger flowers in a bright orange color. Thunbergia fragrans bears 2-inch wide, white, fragrant flowers. The most available variety is called Angel Wings and blooms in about 12 weeks from seed.

Thunbergia, black-eyed Susan vine, clock vine related varieties: Susie Mix is composed of orange, yellow, and white blooms, either with or without dark centers. African Sunset ranges from brick red to cream. Salmon Shades contains a variety of milky oranges.

Wild American Beauty: The Black-Eyed Susan

By Ray Allen, Founder of AmericanMeadows.com

Who was Susan anyhow? And exactly what was her relationship with Sweet William?

Ever wonder about one of America’s favorite wildflowers? Who was Black-Eyed Susan? Her story is one of the grand romantic tales of the wildflowers. And beyond legend, her name graces several of our most important and popular wildflower species. (By the way, the flower’s eye, or center, is not really black; it’s dark brown, but that’s not important.)

Who was she? Well, no one’s sure, but the legend says it all comes from an Old English poem of the post-Elizabethan era entitled simply, “Black-Eyed Susan,” written by a very famous poet of the day named John Gay, 1685-1732. (Painting at right by Winslow Homer.):

All in the downs, the fleet was moored,
Banners waving in the wind.
When Black-Eyed Susan came aboard,
and eyed the burly men.
“Tell me ye sailors, tell me true
Does my Sweet William sail with you?”

There are several stanzas, explaining that her William was on board, “high upon the yardarm”, and quickly scrambled down for a fond farewell with his lady love. It seems he was off to the high seas, but promised ardently to be safe and true:

Though battle call me from thy arms
Let not my pretty Susan mourn;
Though cannons roar, yet safe from harms
William shall to his Dear return.
Love turns aside the balls that round me fly
Lest precious tears should drop from Susan’s eye.

This charming poem tells one of the great “Legends of Love” in our wildflowers, and every summer even today, it plays out just as the poem describes. Here’s how it works:

Even though it’s not a native, if you seed wild Sweet William (Dianthus barbatus) with common Black-Eyed Susan (Rudbeckia hirta), they’ll bloom beautifully for you at exactly the same time. Because both are basically biennials, and her gold plus his bright reds and purples blooming together is a sight to gladden any gardener’s heart.

Since Susan is a North American native, this tale tells us English colonists must have given the golden beauty her name when they arrived in the New World. However, since most all the Black-Eyed Susan species are native to the Great Plains, plant experts have wondered for years how our colonists on the east coast could have given this wildflower the name it’s had for centuries. But some recent research in Maryland (where “Susan” serves as the State Flower) shows that the plant was growing there during the colonial period. So like today, Black-Eyed Susans were probably across the continent from the beginning. Today, they are common in all 50 states and across Canada.

The Botanical Name

The genus name for all Black-Eyed Susans is Rudbeckia. It’s for the Rudbecks, a very famous Swedish father and son both named Olof. Olof the Elder (shown in the photo) lived from 1630-1702 and was a world- famous scientist known mostly for his accomplishments in medicine (anatomy) and liguistics, but was also known for studies in music and botany. Throughout his career, he had the strong support of Sweden’s famous Queen Christina, and was a celebrity at her court. He established the first botanical garden in Sweden, which was originally called Rudbeck’s Garden.

His son, Olof the Younger (1660-1740) continued many of the father’s studies, and became almost as famous in his time as a scientist and professor. One of his best-known students was another

Swedish scientist, Carolus Linneaus, the man who devised our system of plant nomenclature. So it’s no surprise that Linneaus gave the name “Rudbeckia” to this important group of plants. By the way, a hundred years after the establishment of “Rudbeck’s Garden,” it was renamed for Linneaus. And a modern descendant of the Rudbecks is Alfred Nobel, originator of the Nobel Prizes. So it’s safe to say that our lowly, common roadside “weed” has a very prestigious name.

Susan in Our National Culture

Ever since the beginning, the Black-Eyed Susan has figured prominently in things American. Every budding nature photographer has a prized photo, usually with a beautiful butterfly on a Black-Eyed Susan. After all, they’re beautiful, and they’re everywhere. But even the most sophisticated have chosen the “Susan” as a decorative motif. No less than Louis Comfort Tiffany himself immortalized this common wildflower along with much more aristocratic lilies, peonies, irises, and roses with a magnificent “Tiffany Lamp,” now among the most prized American antiques.

And the most visible annual celebration of our own Black-Eyed Susan is in the Sport of Kings, horse-racing. Each year, we all see the “Run for the Roses” which is the Kentucky Derby. But that’s not the only famous run. The “Run for the Black-Eyed Susans” is at Baltimore’s Preakness Stakes, as Maryland honors its state flower, and a horseshoe arrangement of “Susans” is placed around the winning horse’s neck. At the Preakness, Black-Eyed Susans are everywhere!

The Several Species, all North America’s own

Unlike so many others, The Rudbeckias are not a worldwide group of plants. All of the approximately 30 species are North American natives, making the Black-Eyed Susan a decidedly American (and Canadian) wildflower. Here are the most important species:

Our native Rudbeckias (Black-eyed Susans) and their famous hybrids

Wildflower Species Type Description and Height of Wildflower Sample Hybrids from wildflower species
R. hirta Biennial or Annual Familiar roadside “weed” in all 50 states, to 3 ft. Gloriosa Daisy (short-lived perennial)
R. fulgida var sullivantii Perennial Similar to above, to 3 ft, parent to most perennials. “Goldsturm”
R. fulgida var speciosa Perennial A shorter variety to 18″ tall with 1 ½-3″ flowers. “Viette’s Little Suzy”
R. lacinata Perennial Tall with lemon-yellow drooping flowers. To 9 ft. “Golden Glow”
“Gold Drop”
R. nitida Perennial Drooping gold flowers on plants 3-4 ft. tall. “Goldquelle”
“Herbstonne”
R. subtomentosa Perennial Black-Eyed Susan with blunt petals. 4 ½ ft. “Henry Eilers”

Rudbeckia hirta, the favorite roadside wildflower

Rudbeckia hirta (front)

This is the gorgeous gold wildflower you see everywhere—growing on its own, often in great golden sheets of color along the highway, in unused fields, often in “disturbed ground” and maybe in your own backyard. Generations of American children have picked them in proud bouquets, and they figure importantly in our culture. With apologies to our Canadian neighbors, I’ve always thought it is the quintessential American wildflower, since it is so widespread and so common, yet so beautiful, it symbolizes the American ideal of opportunity for all, enjoyed and available to everyone from our earliest natives and settlers to every American child alive today. It’s definitely my favorite.

Best of all, for gardeners, it’s a snap to grow from seed, and is a staple of any good wildflower seed mixture. Because these beautiful flowers can easily be one of the major color-makers in any North American wildflower garden.

However, the exact way it performs depends on where you live. It usually grows as a biennial, which means it takes two years to bloom from seed. Biennials live only two years, and bloom only their second season, then die after reseeding heavily. However, in some regions, R. hirta grows as an annual, blooming the first year. In other areas, experts insist it’s perennial. In all my years of wildflower gardening, I’ve never seen it perform as a perennial. But most of my gardening has been in very warm (Florida) or very cold (Vermont) eastern U.S. climates.

Two things for sure: In Vermont, Rudbeckia hirta is a classic biennial. From fall or spring seeding, it germinates quickly, forming a basal rosette of its signature “hairy” green leaves, and that’s all it does. The elegant bloom stalks arise the second summer.

In Florida, with no frost, the same seeding will bring bloom late in the summer, which leads many southern gardeners to consider the plant an annual. All this means is that it will bloom the first year as long as the growing season is long enough. For example, garden expert Allan Armitage, who lives in Georgia, calls the common wildflower an annual, and reports that Rudbeckia hirta, seeded naturally in the fall, begins blooming for him and his wife (Susan) the first week of June, and continues for two months.

R. hirta gloriosa, The Gloriosa Daisy

Rudbeckia hirta (front)

The short life of the non-perennial form tempted many hybridizers to try to create a more-perennial plant from this popular wildflower. The most successful, and a sensation when it appeared, was The Gloriosa Daisy, introduced by the W. Atlee Burpee Seed Company in the 1950’s. This strain, still widely grown from seed, creates a plant a bit larger than the common wildflower, with blooms that are totally different. First of all, the flowers are about three times the size of the wildflower’s blooms—often 6″ across. And “Gloriosas” are always a mixture of pure yellow and splashy bicolors, most with dark mahogany red splotches at the base of the petals, creating a stunning pinwheel effect. Others in the mix are fully double. But all the flowers are large, making the Gloriosa strain a big favorite. However, while the blooms are spectacular, the perennial qualities are weak. Most stands of Gloriosa Daisy will “run out” in about 2-3 years in a very cold climate, earning them the dreaded name, “short-lived perennial.” For dependably perennial plants, the hybridizers had to turn to other Rudbeckia species.

Rudbeckia fulgida, the great look-alike perennial wildflower, and R. “Goldsturm”

The great confusion among the Rudbeckias arises from the fact that the native biennial (R. hirta) and an important hardy perennial species (R. fulgida) look almost exactly alike. So many laymen don’t realize that the beautiful roadside “weeds” they see are botanically different from the long-blooming perennial clumps seen in almost all American perennial gardens—from home gardens to those “decorative plantings” at shopping malls and gas stations. They’re everywhere, since the perennial Black-Eyed Susans are some of the most useful landscape plants of them all, when it comes to dependable every-year long-blooming mid-summer color.

R. fulgida is the native base for most of the hybridized perennial Black-Eyed Susans, and they descend from various “varieties” of the species. This means naturally-occurring variations, but still the same basic plant. Rudbeckia fulgida has four recognized varieties, botanically introduced with the abbreviation, “var.” Here are the two important ones you may see at the garden center or in catalogs:

Rudbeckia fulgida var sullivantii

Rudbeckia ‘Goldsturm’

This variety is the parent of the king of all the commercial perennials, a plant commonly called Rudbeckia ‘Goldsturm’. That’s German for “gold storm,” and a gold storm it is. This fantastically successful perennial introduction, developed in Germany, is one of the most popular and widely-planted flowering plants in America, and justly so. The flowers are clear, golden yellow, and a bit larger than the wildflower, but very much the same. Each plant, once it matures, puts up a whole bouquet (probably 20) of these big flowers and holds them in bloom for weeks, even in the heat of mid-summer. This is the kind of plant every perennial gardener loves. Today, “Goldsturm” is super-popular worldwide.

Rudbeckia fulgida var speciosa This variety of the species (sometimes referred to as var newmanii) is much the same as the one above, and is the parent of several other well-known garden perennials including “Viette’s Little Suzy.” It has similar standard Black-Eyed Susan blooms, but is shorter, growing to only about 18″. This one is named after a famous family of hybridizers in the US, descended from Martin Viette, a Swiss gardener who arrived on Long Island in 1920. He and his family have created a long list of excellent new perennials, and this is one of them.

C. Rudbeckia lacinata, the very tall parent of “Golden Glow”

Rudbeckia lacinata ‘Golden Glow’

It grows so tall in the wild (up to 9ft.) it’s often assumed to be a sunflower, but it is not. The flowers are very large with drooping petals, colored a pale lemon yellow. The species can be quite impressive in a wildflower meadow, since the big flowers and petals often flutter’ in the breeze, standing above other plants. But it’s too big for most gardens.

This species is best known as the wild parent of one of your great-grandmother’s favorite flowers, Golden Glow. It is a tall plant, up to 5 ft, which was introduced in 1894. The yellow blooms are fully double, and resemble a bright yellow chrysanthemum. Not very popular and not so well known today, they, like the parents, are often assumed to be short sunflowers or tall mums. Golden Glow forms clusters of flowers on the tall stems which are famous for “toppling over” as the flowers open. Millions of gardeners have rigged stakes to keep old Golden Glow plants standing tall with their beautiful blooms. They are some of the toughest, longest-lasting perennials in old gardens. A shorter version is called “Golden Drop,” and grows to only 2-3 feet.

E. Rudbeckia nitida, another tall one with large, golden flowers.

This species is tall like R. lacinata and has a distinctive greenish color in its center. From this wild beauty, the hybridizers have created a sensational plant called R. nitida “Herbstsonne”, a tall (60-72″) perennial with colossal golden flowers. The petals are wide and beautiful, and droop somewhat, but the plant makes a spectacular, elegant show. Another hybrid called “Goldquelle” is shorter with double flowers.

F. Rudbeckia subtomentosa, another wild one with somewhat different flowers.

This Black-eyed susan is native to the central US from Wisconsin to Texas. It grows to only about 4 ½ ft, and its flowers are distinguished by blunt tips on each petal. A commercial cultivar from this species is “Henry Eilers”, which grows to 4 feet and has large, tubular petals with blunt tips.

The Black-Eyed Susan Vine is not

Trading on the fame of the real thing, someone named a small tropical vine that grows easily indoors the “Black-Eyed Susan Vine.” Surely that was smart marketing, but that little vine with its little yellow trumpet blooms is Thunbergia alata, nowhere near the Rudbeckia genus.

Close Relatives, other “Coneflowers”

Though the vine has nothing in common but flower color, there are other North American wildflowers who are close relatives. In fact, several of them were once considered Rudbeckias, but are now more correctly classified in their own genus. The now very famous medicinal, Echinacea and all its hybrids are called “Coneflowers,” with Echinacea purpurea, the Purple Coneflower, as the best known. The Prairie Coneflower (yellow) and Mexican Hat (red), both named Ratibida columnaris, are closely related, as is the Grey-Headed Coneflower, Ratibida pinnata. These are all close relatives, but not Rudbeckias.

The Invaders: Rudbeckia

There are several different flowers often called black-eyed Susan, but I have figured out that mine are probably the popular variety Rudbeckia fulgida ‘Goldsturm’. It is sometimes also called the orange coneflower (although many people consider the only true coneflowers to be the members of the related genus Echinacea, and the cultivar ‘Goldsturm’ isn’t orange. The “true” black-eyed Susan is the closely related Rudbeckia hirta, which is also sometimes called the ox-eye daisy; though it is not, of course, a daisy.

The rudbeckias and echinaceas are both perennial members of the aster family, which also includes chrysanthemums, daisies, sunflowers, and of course true asters. While it may be difficult to tell the rudbeckia species apart by their flowers, the form of the leaves is different. R. fulgida (left) has long, teardrop-shaped toothed leaves, dark green in color, sometimes tinged purple; the leaves of R. hirta (right) are paler in color, more narrow, less toothy, and leaves and stems are hairy.

Because the Rudbeckias are native plants of North America, some people will say I can not properly call them “invasive” here. Fine, but they certainly do spread! While they seed themselves, they spread more readily by runners that sneak along just below the surface of the earth, popping up new plants every couple of inches. These new plants are insidiously tiny above ground, hard to spot and harmless-looking at first. But they are rooted quite tenaciously and do not willingly let go of the earth. Before long, each one is firmly established and sending out new runners of its own.

Of course the defenders of rudbeckia would say that you want a desirable plant to spread, and, to an extent, this is true. When I accepted these plants from my friendly neighbor, I was happy to find a plant that would flower later in the year. The section of the garden where I put them already had painted daisies, which make a fine show in May and June but die back in the mid-summer heat. Rudbeckia follows them quite effectively. The bright gold flowers are attractive and stand for weeks, providing bloom for the rest of the year, into fall.

If only they would stay where I put them, the way the painted daisies do! If only they wouldn’t insinuate themselves into the roots of the other plants! If only they were more easily pulled out when they do! But no, so there you can find me on my knees with my garden paring knife, carefully dissecting out the upstart new sprouts of rudbeckia from the rhizomes of the Zebra Iris. It is at such times when I contemplate the fact that there is far more than one flower calling itself the Black Eyed Susan, and that somewhere is a variety that is just as attractive, blooms just as long, and doesn’t spread at quite such a rampant rate. If only I had taken the trouble to find it, instead of taking the neighbor’s unwanted plants off her hands.

The next time some cheerful neighbor comes offering me excess plants, I hope I will remember that there is probably a reason why she wants to get rid of them.

Dogs aren’t very picky. Besides their dog food they’ll happily snuffle and scarf up anything they come across, from the contents of a baby’s diaper to the newly planted flower bulbs in your garden. And while some of the stuff your pooch comes across is just gross (like said diaper content), other items can be downright dangerous. In fact, there are some plants that are poisonous to dogs and can actually kill them.

That’s why if you are bringing a new dog into your life you should definitely pet-proof your house, says Dr. Ann Hohenhaus, a veterinarian at Animal Medical Center in New York City. Get rid of any houseplants—and scour the backyard for plants that are poisonous to dogs.

Plants That Are Poisonous to Dogs

  • Autumn crocus – This highly toxic plant can cause your dog to vomit profusely and lead to gastrointestinal bleeding and liver and kidney failure. Worse, the symptoms may not show up for days. Learn more>>
  • Azalea – This popular outdoor plant can cause drooling in your dog as well as vomiting and diarrhea. If you don’t get your pet to a vet quickly, she could also fall into a coma.
  • Cyclamen – Eating any part of this flowering plant, also known as Persian violets, can cause drooling, diarrhea, and vomiting. If your dog gobbles up a lot of flowers, leaves or roots, her heart rate may be affected.
  • Daffodil – Toxic ingredients in daffodil bulbs can hurt your dog’s mouth, and cause vomiting and diarrhea.
  • Dieffenbachia – This popular houseplant is also known as Dumb Cane. While it won’t kill your dog if she eats it, she’ll have diarrhea. Eating the plant can also make preexisting conditions like irritable bowel syndrome or diabetes worse in a pet.
  • Hyacinth – This popular flower can cause lots of drooling, diarrhea, and vomiting. But if your dog eats too many bulbs, it can affect her heart rate and breathing.
  • Jonquils – Like daffodils, these flowers can irritate your dog’s mouth and cause vomiting and diarrhea.
  • Lily of the valley – This plant can cause vomiting, diarrhea, heart failure, and seizures. Learn more>>
  • Oleander – Extremely toxic, this popular outdoor plant contains cardiac glycosides that harm the heart, decrease body temperature, cause abnormal pulse rates, and even death.
  • Paperwhites – These flowers can irritate your pooch’s tongue and mouth and cause vomiting and diarrhea.
  • Philodendron – These popular houseplants can irritate your pup’s mouth and cause nausea and vomiting.
  • Poinsettia leaves and flowers – This is only a mildly toxic plant to dogs. Still, it can irritate the skin around your pup’s mouth and eyes, and cause vomiting, diarrhea, and drooling.
  • Rhubarb leaves – Although the stalks are used to make pies, the leaves are mildly toxic to dogs. Symptoms include vomiting, diarrhea, tremors, and bloody urine.
  • Sago palm – If your dog nibbles on the palm leaves of the plant, she’ll have an upset stomach, which can lead to liver failure, seizures, and even death a few days later.
  • Tulips – Like hyacinths, digging up and eating a few tulip bulbs can cause drooling, diarrhea, and vomiting. But if your dog really chows down, it can affect her heart rate and breathing.
  • Yew – The plant and the red berries are extremely toxic to dogs, and can cause cause seizures, cardiac failure, life threatening changes to blood pressure, and even death.

Poisonous Plant Rx

If you haven’t gotten rid of these plants yet, be on the alert for signs that your dog has been poisoned. Sometimes the signs are subtle—your dog is drooling or licking her lips. Other times, she may be running around frantically because the plant is irritating her mouth or the skin around it. Still other times, your dog may be throwing up or panting excessively.

Don’t attempt to treat your pet at home, warns Hohenhaus. While you may have read that giving your dog hydrogen peroxide can get her to throw up, Hohenhaus says your vet has better drugs to induce vomiting. Besides, you don’t want to waste valuable time hunting for the peroxide and trying to pour it down your pup’s throat. Better just to head for the ER.

If you aren’t really sure what your pet ate, you can call the ASPCA’s animal poison control hotline, which has the most up-to-date information, at (888) 426-4435, suggests Hohenhaus. And it wouldn’t be a bad idea to tape the number to your fridge, either, she adds.
