Holly Shrubs For Zone 5: Growing Holly Plants In Zone 5
Holly is an attractive evergreen tree or shrub with shiny leaves and bright berries. There are many species of holly (Ilex ssp.) including the popular ornamentals Chinese holly, English holly and Japanese holly. Unfortunately, for those who live in chilly zone 5, few of these are hardy holly varieties. However, growing holly plants in zone 5 is possible if you select carefully. Read on for information about choosing holly shrubs for zone 5.
Hardy Holly Varieties
You’ll find over 400 species of holly in the world. Many are broadleaf evergreens and offer glossy leaves and bright, bird-pleasing berries. The species range in zone, shape and cold hardiness. Hollies are not demanding or difficult plants to grow. However, before you start growing holly plants in zone 5, you’ll want to check their cold hardiness.
Chinese, English and Japanese holly shrubs are not hardy holly varieties. None of these popular plants could be used as zone 5 holly shrubs since none survive zone 5 winters, which can get between -10 and -20 degrees Fahrenheit (-23 to -29 C.). These species are sometimes hardy to zone 6, but cannot survive the temperatures in zone 5. So are there holly varieties for those residing in zone 5? Yes, there are. Consider American holly, a native plant, and the blue hollies, also known as the Meserve hollies.
Holly Shrubs for Zone 5
The following holly shrubs are recommended for growing in zone 5 landscapes:
American holly (Ilex opaca) is a plant native to this country. It matures into a lovely pyramid-shaped tree that grows to 50 feet tall with a 40 foot spread. This type of holly thrives in USDA hardiness zones 5 through 9.
Growing the shrub in zone 5 is possible if you plant American holly and site it where it receives four hours or more of direct, unfiltered sunshine per day. This holly shrub needs soil that is acidic, rich and well-drained.
Blue hollies are also known as Meserve hollies (Ilex x meserveae). They are holly hybrids developed by Mrs. F. Leighton Meserve of St. James, New York. She produced these hollies by crossing prostrate holly (Ilex rugosa) – a cold hardy variety – with English holly (Ilex aquifolium).
These evergreen shrubs are more cold tolerant than many types of holly. They have leathery dark blue-green leaves with spines like English holly leaves. Growing these plants in zone 5 is easy. Plant the cold hardy holly shrubs in well-drained, moist soil. Choose a location where they will get some shade in summer.
If you are looking for zone 5 holly shrubs in this group, consider the blue holly cultivars ‘Blue Prince’ and ‘Blue Princess.’ They are the most cold hardy of the series. Other Meserve hybrids that can serve the landscape well include China Boy and China Girl.
Don’t expect rapid growth when you are planting Meserve hollies. They will get to about 10 feet tall in time, but it will take them quite a few years.
Holly’s big plant family includes hundreds of varieties that range from 70-foot-tall trees to petite shrubs less than a foot tall. Along with sizes, these trees and shrubs come in a variety of forms: columnar, pyramidal, rounded, or weeping. Their foliage varies, too, ranging from large, spiny leaves to smooth, small leaves that resemble boxwood. Even holly’s berries come in a variety of hues that include red, pink, blue, orange, yellow, and white. Nearly all of these variations can be sorted into four basic groups: English holly (glossy, spiny foliage); American holly (similar to its English cousin, but with duller leaves); Chinese holly (large glossy, spineless varieties); and Hybrid holly. In other words, there is probably a holly in this diverse plant group that suits your landscape. Check with a trusted local nursery or extension office to learn about the best holly species for your region.
Holly provides year-round interest while serving as part of a hedge or perennial border, or in foundation plantings. Its glossy leaves add a refreshing touch to the growing season, even when blending in with other plants. Evergreen varieties take center stage in winter when they anchor leafless garden beds. Tall evergreen hollies are good for creating a dense hedge or screen. When used as barrier plants, holly varieties with spiny leaves are nearly impenetrable. No matter where you plant holly, if pollinated its colorful berries add splashes of winter color and food for birds.
Make a holly wreath for an inviting door decoration.
Many holly plants will produce colorful fruit that remains in place for three to six months of the year, depending on the density of the wildlife population. Whether you want to showcase these colorful berries in the yard or use them to perk up holly branches in an arrangement, you need to have separate male and female plants near each other in the landscape. Female plants depend upon the males for pollination in order to produce berries. Check plant tags carefully when purchasing holly to ensure you buy at least one male plant to pollinate 10 to 20 female cultivars. Choosing a male and female of the same variety helps make sure the plants bloom at the same time—a key factor if you expect bees and other pollinators to work their magic. Be careful about the resulting berries; if eaten by humans or pets, gastrointestinal distress may follow.
These are the best berry plants for birds.
Holly Care Must-Knows
The best time to plant holly is in the spring, with plenty of warm weather on the horizon. Read plant tags carefully when selecting a planting site for holly. Some hollies prefer full sun, while there are evergreen varieties that grow best in areas where they receive part shade in winter. Most varieties prefer moist, well-drained loamy soil that is slightly acidic. Winterberry, on the other hand, grows well in boggy soil. This plant appreciates a moderate amount of water; usually rain will do the trick. Provide supplemental waterings on a weekly basis during times of drought. Fertilize in spring and fall to keep plants at their best.
Holly shrubs don’t typically require pruning unless they become unwieldy or you want to create a hedge or geometric shape. On the question of whether or not (and when) to prune, the holly family is so diverse that it’s impossible to give one answer that will work for all varieties. In general, wait until dormancy for most hollies. Pruning in late fall or early winter means you can use the clippings in holiday arrangements or wreaths. On the other hand, if you prune in late winter you can enjoy seeing the berries outside. Either way, the trade-off is you’ll be removing old wood required for blooming—and therefore future berries. There is no single right answer. Just don’t prune in late summer when the plant will put out new growth that will die when frosts arrive. Worth noting: Late spring is a good time to prune holly bushes into hedges.

Garden Plans For Holly
Blue Hollies: Premier Evergreens for Northern Gardens
The development of the blue hollies in the 1960 and ’70s was a blessing since they provided a hardy plant with very attractive year-round appeal. The red berries, often carried through the winter months, was an added bonus, especially during the Christmas season. There are a surprising number of blue holly selections on the market, varying from under 75 cm to over 5 m. This article will introduce you to the wonderful diversity of the blue holly.
One of the most popular broad-leaved evergreens for gardeners are hollies. Their glossy, deep-green foliage is appreciated all year. And for the Christmas season, nothing looks nicer than an arrangement featuring holly stems adorned with bright red berries. If you are into attracting birds to your garden, hollies are excellent as they are eagerly sought by robins and waxwings (much to the dismay of those who want to enjoy the berry display through the winter months!) Traditionally in Europe, the English holly, Ilex aquifolium, was the holly species of choice. In the U.S., the American holly, I. opaca is a similar counterpart, while in China, it’s the Chinese holly, I. cornuta. Unfortunately, northern gardeners (zone 5 or colder) could not enjoy these trees and shrubs since the previous ones mentioned are mostly rated for zone 7 or mild areas of zone 6. There is a super hardy (zone 4) species from China called I. rugosa but unfortunately, that species is rather rangy with far less attractive foliage. Thankfully, holly are rather promiscuous and will readily hybridize between species. Plant breeders took advantage of this and created a cross between the hardy but inferior I. rugosa and the very attractive but more tender I. aquifolium. The resulting offspring had the best qualities of both parents; excellent foliage on a dense, compact, hardy (zone 4) shrub. These hybrids are commonly called the blue hollies or Ilex X meserveae, in honour of the creator of the first blue holly, Mrs. F. Leighton Meserve of St. James, New York, way back in the early 1960s.
At this point I should point out that hollies are what botanists call dioecious plants; plants are functionally either male or female. Both produce small, rather insignificant white flowers in late spring. If a male and female are close enough, the female flowers will be fertilized by pollinating insects, resulting in the red berries we associate with hollies. Males are very effective at producing pollen, so one male plant can ‘service’ several nearby females. In fact, the males can service several closely related species, resulting in hybrids, of which the blue holly are an example.
The earliest released blue holly were the cultivars ‘Blue Boy’ and ‘Blue Girl’, released in 1964. These earliest selections, while not as dense as later introductions, are still worthwhile plants. Both grow to 3 m tall and wide, but can be clipped to keep them smaller. Released in 1972 and 1973 respectively, were ‘Blue Prince’ and ‘Blue Princess’. These are the standard blue hollies offered in the trade. Plants are very dense with deep-green, glossy foliage and attractive purple stems. Both may reach to 4 m in milder areas but rarely exceed 2 m at their northern range of hardiness. They may be clipped to maintain shape and denseness. ‘Blue Princess’ is not only among the most productive berry producer of any holly species or hybrid, their berries are also among the darkest red. For something a little different, you can try ‘Golden Girl’, whose fruit are yellow rather than the traditional red. More recently have come the selections ‘Blue Maid’ and ‘Blue Stallion’. Both grow faster than ‘Blue Prince/Princess’ and can reach even taller. They are reported to be hardier than the previous cultivars. ‘Blue Stallion’ has the least spiny foliage of any blue holly selections. Perhaps the loveliest hybrid is ‘Blue Angel’. It resulted from backcrossing I. X meserveae to I. aquifolium. The resulting offspring look even more like English holly but alas, has inherited some of that species tenderness, thus is only reliable in zone 5.
If variegated foliage is your preference, then try to obtain ‘Honey Maid’, ‘Honey Jo’ or ‘Gretchen’, all which sport yellow-margin foliage. These are all females and produce red fruit, providing a wonderful contrast to the variegated leaves. The newest introductions, developed in Germany, are ‘Castle Wall’ (male) and ‘Castle Spire’ (female) which exhibit a fastigiate to pyramidal habit not unlike Hick’s Yew. These selections grow 2-2.5 m tall but only 1 m wide. For limited space, you can try ‘Little Rascal’, a dwarf which will reach 0.5 to 1.5 m. The foliage of this selection turns purple in winter.
Included among the blue hollies are hybrids between I. cornuta and I. rugosa. The two most popular selections are ‘China Boy’ and ‘China Girl’. Both can reach 3 m and are perhaps even a tad hardier than the standard blue hollies noted earlier. They are certainly more heat-tolerant. A characteristic inherited from I. cornuta are their leaf margins which arch downwards giving the leaves a distinctive cupped appearance. Also included among these hollies is ‘Dragon Lady’, a hybrid between I. pernyi and I. aquifolium sometimes referred to as I. X aquipernyi. This one has a strong upright, pyramidal habit and may reach 6m! To reiterate an earlier note, any of the male cultivars noted above will pollinate any of the above noted females.
Cultivation is quite simple. Full sun is best for maintaining a dense habit and maximizing fruit production, but part shade is certainly tolerated. Although hardy to zone 4, avoid windswept locations. The soil should ideally be moist yet well-drained, with a slightly acidic pH. Uses include foundation plantings, informal hedges and spiny barriers. Hollies are surprisingly resistant to both insects and diseases. With relatively few broad-leaved evergreens suitable for northern gardeners, the blue hollies have become indispensable landscape plants and a much appreciated addition to our winter gardens.
