Plants with red flowers

Do you absolutely love gardening? Are you passionate about your garden? Why not show it by adding in some gorgeous red annual flowers this year?

Red is a gorgeous color, one that can’t help but draw the eye and turn some heads. One of the best things about adding red to your garden is that the type of flower itself transforms the shade into a variety of symbols. You can add in a funky flower to evoke whimsy, a rich-blooming rosette to evoke love and passion, and even a spire-shaped bloom to add intensity and boldness.

We’ve put together a list of 10 stunning red annuals that are sure to add an element of bold beauty to your garden.

Celosia

This stunning beauty comes in a kaleidoscopic variety of exquisite colors, red being one of the real showstoppers of the group. The striking spires of Celosia blooms have twisted fire-like shape that easily resembles a fiery sunset. Be careful not to overwater these funky flowers. Instead, plant them in a well-drained area and lightly mist the blooms. Celosia is a delicate flower to care for and will grow best in zones 10 and 11. These flowers also can be hung upside down and dried to preserve their beauty.

Begonia

These warm-loving flowers are a container and box-garden favorite, originally found in tropical and subtropical forests. Begonias are constant bloomers, making them a perfect addition for a summer garden or grown in a windowsill. Their fancy foliage has interesting markings and designs that make the leaves just as lovely as the blooms. These flowers grow well outdoors in zones 9-11 but make good houseplants in almost any region if they are kept relatively warm and receive sunlight.

Chrysanthemum

Also called mums, Chrysanthemums are popular decorative flowers because of the meaning associated with each color, the red chrysanthemum conveying love. While their blooms come in varying forms, these decorative flowers are most often seen with daisy-like petals and decorative interior pompon-style buttons. They bloom well in a garden when kept dry with at least five hours of sunlight in zones 5-9.

Dahlias

The spiky, daisy-like blooms of a red dahlia make it a truly exquisite addition to any garden. Dahlias are showy bloomers, flowering from summer all the way through late fall. They are often grown to be used as cut flowers around the house and they play well with other flowers as well as vegetables. Dahlias are very susceptible to frost and can be grown in zones 2-11 when gardeners take special care to avoid frost.

Geraniums

These beautiful flowers are an easy-to-grow garden favorite, even flourishing when moved indoors during the colder months. Red geraniums are rich in hue and, like all geraniums, emit a delicate scent from their bundles of pleated, rosette blooms. They look wonderful in window boxes and pots. Geraniums will grow best in zones 10 and 11, but they can often be grown down to zone 7 if they are carefully tended to.

Impatiens

Impatiens is a garden favorite due to their hardiness and ability to flourish in zones 2-11, even being able to withstand very dry soil. Red impatiens is very cheerful flowers, with five broad petals and a deep purple center eye. They make excellent border plants and also do well in containers. Impatiens prefer at least partial shade.

Petunias

Petunias come in a variety of lovely colors that are treasured for their lasting color and simple care. The trumpet-shaped 3-4” blooms grow upright and look especially lovely when they are allowed to spill over a garden border or container edge. Petunias grow best in zones 9-11, but they can also excel in slightly colder zones when properly cared for.

Zinnia

Want an exceptional burst of fierce red in your garden? Add red zinnias along with several other colors of this easy-to-grow flower to attract butterflies all summer long. Zinnias are excellent cutting flowers, with one daisy-like bloom sprouting off each separate stem. This hardy flower will thrive in zones 3-10.

Verbena

Verbena is prized by gardeners for the old-fashioned appearance of its fragrant, fern-like flowers. The brilliant blossoms of Verbena bloom in clusters of bold colors and have frolicsome white eyes. Verbena will grow to its prime in zones 7-11.

Nemesia

Most commonly used as a bedding plant in summer gardens or in a hanging basket, Nemesia has fan-like petals that gather around a bright center eye. Nemesia can be grown as an annual plant in zones 2-11 and can thrive as a tender perennial in zones 9-11.

Best Garden Flowers for Color All Summer

Blooms You Can Bet On

No doubt you’ve heard that a well-designed garden should include plants prized for their striking foliage, as well as some that produce fall color or berries, and others that provide good structure in winter. But lets face it: most of us want flowers. Lots of them. All the time. That’s where the summer flowering plants below come in. They’ll churn out blooms for weeks on end this summer. In most cases, you can harvest armloads to fill vases or give away, and still have plenty left to enjoy in your garden beds long past Labor Day.

Perennial Hibiscus (H. moscheutos)

Photo by Indu Singh

Also known as rose-mallow and swamp hibiscus, this garden standout was bred from wildflowers native to the East and South. Huge red, pink or white flowers can be as much as a foot across on stems that range from 2 to 8 feet high, depending on the variety. Flowers bloom from late spring until frost. Stems die back to the ground each winter.

Requires full sun; regular to abundant water. Grows as a perennial in zones 5-10.

Purple Wave Petunia (Petunia F1 ‘Wave Purple’)

Before 1995, when this hybrid was named an All-America Selection winner, gardeners thought of petunias as upright plants. Purple Wave petunias (and later Wave introductions in pinks and lilac) are more like vines—perfect for growing in hanging pots, along retaining walls or even as a ground cover.

Requires full sun; regular water. Grows as an annual in all zones.

Profusion Zinnias (Z. hybrida)

Grow zinnias if you want to be able to cut armloads of flowers for bouquets and still have a bright band of color alongside a path or a lawn. All zinnias thrive in hot weather, but Profusion zinnias keep on blooming well into fall, whatever the weather. Profusion White, Orange and Cherry, which have daisy-like flowers, each have won multiple garden awards. If you want fluffy pom-poms, look for double Profusion varieties in cherry, gold, white and “fire,” an orange-red.

Requires full sun; regular water. Grows as an annual in all zones.

Globe Amaranth (Gomphrena globosa)

For year-round enjoyment, these clover-like flower heads are hard to beat. The papery flowers last a long time in the garden and in fresh bouquets, and the blooms are easy to dry for use in wintertime arrangements. Depending on the variety, flowers are white, red, pink, lilac or purple. ‘Strawberry Fields,’ with bright red blossoms, and ‘All Around Purple’ are two standouts.

Requires full sun to partial shade; moderate water. Grows as an annual in all zones.

Sea Holly (Eryngium)

If you want to add contrast to a flowerbed or to fresh or dried flower arrangements, this dramatic spiky plant is a great choice. It resembles thistle, but the flower colors blend in more with the prickly blue-green leaves, which are often streaked with silver. Alpine sea holly (E. alpinum) is a deep steel blue, while E. amethystinum is more silvery blue. Miss Willmott’s Ghost (E. giganteum) produces especially striking conical flowers, each surrounded by a wreath of silvery, spikey bracts.

Requires full sun; moderate to regular water. Grows as a perennial in zones 3-8.

Stella de Oro Daylily (Hermerocallis)

Tough and trouble-free, daylilies produce showy flowers above a mound of sword-shaped leaves. Whether in the garden or in a vase, each blossom lasts just one day; they are daylilies, after all. But each stem holds numerous buds that open on successive days. Low-growing Stella de Oro keeps churning out new stems with a profusion of golden-yellow blossoms for up to five months, far longer than most daylilies.

Requires full sun to light shade; regular water. Grows as a perennial in zones 3-9.

Evergreen Candytuft (Iberis sempervirens)

Small clusters of delicate white flowers appear in low-growing clumps in spring, and continue into the fall. The shiny, dark-green leaves stay on all winter, so the plant remains attractive year-round.

Requires full sun to part shade; regular water. Grows as a perennial in zones 5-9.

Brown-Eyed Susan (Rudbeckia)

Brilliant yellow or orange flowers with a raised brown polka-dot center stand out in a perennial border. R. hirta varieties bloom from seed the first year and are grown as annuals; in the warmest areas, they’re wintertime bloomers. Most other kinds are perennial and gradually form showy, spreading clumps as hardy as their wildflower ancesters, native to the East. All are good cut flowers as well. One to search out: R. fulgida var. sullivantii ‘Goldsturm,’ an especially flower-covered variety.

Requires full sun; moderate to regular water. Grows as an annual or perennial, depending on the variety (as noted), in all zones.

Joe Pye Weed (Eupatorium species)

Despite the scary name, this is a lovely wildflower native to our Eastern meadows that draws butterflies and birds. One especially showy variety, E. maculatum ‘Gateway,’ has wine-red stems 5 to 7 feet tall, topped by dusky rose nosegays a foot across. Use as a tall anchor in a perennial bed or as a temporary screen, since stems die back to the ground in winter.

Requires full sun; average to abundant water. Grows as a perennial in zones 4-8.

Purple Coneflower (Echinacea purpurea)

Pink to purple daisy-like flowers about 4 inches across cover this perennial from mid-summer into autumn. The plant is especially hardy and unfussy, and you can divide clumps after several years to get new plants. The flowers draw butterflies and last well as cut flowers. ‘PowWow Wild Berry,’ which has rosy pink flowers, was chosen as an All-America Selections winner for 2010.

Sunflowers (Helianthus annuus)

With large, easy-to-plant seeds and magnificently showy flowers, sunflowers are perhaps the perfect flower for kids to grow. Classic single-stem kinds such as ‘Mammoth Russian’ and ‘Russian Giant’ grow 10-15 feet tall and produce plate-size flowers with edible seeds. Newer, shorter kinds include ‘Ring of Fire,” which is about 4-5 feet tall and has 5-inch flowers that work in a vase, and ‘Sunspot,’ which grows just 2 feet tall. ‘Indian Blanket’ is a branching kind with numerous smaller flowers suitable for cutting. Sunflower blooms face the sun, so choose a bed where the sun will be behind you.

Requres full sun; regular water. Most grow as annuals in all zones.

Marigolds (Tagetes)

These perky yellow or orange flowers really light up a garden bed. The plant’s distinctive (should we say strong?) odor also keeps pests away. Marigolds are great as cut flowers, too. ‘Moonsong Deep Orange,’ a hybrid that was named an All-America Selection winner for 2010, has frilly, densely packed flowers. But many other marigolds look more like daisies, with just a row or two of petals around a dark center.

Requires full sun; regular water. Grows as an annual in all zones.

Plants with red flowers

The colour of red flowers is caused by the presence of certain biological pigments in the petals, such as carotenoids, anthocyanins and betalains.

Red-flowered plants, chosen wisely, can be the crowning glory of a planting scheme. Grow them alongside plum-coloured blooms for a sumptuous border or container display. Or combine with zingy oranges and cornflower blues for bolder effect.

Plus, hot borders wouldn’t be complete without red blooms combined with spicy yellows and oranges.
