Meet the Ilex Genus - Holly Trees and Shrubs
Holly Tree

Holly trees and shrubs are classified as Ilex spp. and are the only genus that belongs to the Aquifoliaceae family. They can be deciduous or evergreen and form into trees, shrubs or lianas.

Many (though not all) species have leaves that either feature spiny teeth or serrated edges. Spiny species can serve well in creating privacy barriers.

Almost all holly species are dioecious, meaning that you will need to plant both males and females if you desire fruit. One male plant is able to pollinate a few female plants. They produce drupes (not berries) that are often red, but may come in shades of white, yellow, purple or black. They are at least somewhat toxic if eaten, so consider that fact if planting in a spot visited by small children.

If you only have room for one holly plant, there are cultivars that are able to produce fruit without pollination in a process called parthenogenesis. One of the most popular parthenogenic cultivars is ‘Nellie R. Stevens’, which resulted from a cross between hybrid between English holly (Ilex aquifolium and Chinese holly(Ilex cornuta).

At first, holly was a part of pagan celebrations in the winter. The Romans used it for Saturnalia. Over time it began to be associated with the Christmas season. The two species most often used for decorations are the American holly (Ilex space) and the English holly (Ilex aquifolium).

American holly is often used as a substitute for English holly (Ilex aquifolium) in Christmas decorations where the latter does not grow well. They are similar in appearance with ​spiny-toothed leaves and an abundance of red berries.

If you only have room for one American holly tree, look for the 'Croonenburg' variety. It is able to pollinate itself because it has male and female flowers on the same plant. If you would prefer yellow fruit, choose 'Canary'. There is also a natural version called f. xanthocarpa.

In 1939, American holly was named as the state tree of Delaware.

Scientific Name: Ilex opaca
Other Common Names: Hummock holly, dune holly, scrub holly
Native to: Southern and eastern United States
USDA Zones: 5-9
Height: 15-60' tall
Exposure: Full sun to part shade

Carolina Holly

The Carolina holly is a deciduous species. It can grow well in sandy soils, which makes it easy to see why another common name for this is sand holly. Bright red fruits are produced in the fall, though they tend to fall off easily which removes the potential for winter interest.

If you have a location that tends to be a bit wetter than most plants like, consider hunting down a dahoon holly. These small trees are naturally found in swampy areas. It has three varieties: Ilex cassine var. cassine, Ilex cassine var. angustifolia and Ilex cassine var. mexicana. Some botanist also consider the myrtle-leaved holly to be a variety of this species.

When someone mentions holly, especially in conjunction with Christmas, they often mean the English holly. Its familiar shape is the one used to adorn Christmas decorations and inspire songs. This is the type species for holly.

There are cultivars available with characteristics like variegated leaves (ex: 'Monvila' - Gold Coast) or golden/apricot fruit (ex: 'Apricot Glow'). The blue hollies or Meserve hollies (Ilex × meserveae) are the result of crossing this species with Tsuru holly (Ilex rugosa).

Scientific Name: Ilex aquifolium

This is one of the deciduous holly species and handles cold better than some of the other species. If you prefer a cultivar with yellow fruit instead of the more common red ones, choose ‘Leucocarpa’ (which may also have white fruit), 'Sundrops' or ‘Xanthocarpa’.

A cultivar named 'Sparkleberry' with bright red berries is the result of a cross between this species and the common winterberry (Ilex verticillata)

Scientific Name: Ilex serrata

Yerba Mate

Tea made from this plant is traditionally placed inside a gourd and served with a metal straw in South America. These straws are capped at the end with a piece full of small holes. They allow one to drink the tea without sipping up bits of leaves. The foliage contains caffeine and theobromine, which are also found in cacao beans. Some studies suggest that there may be health benefits offered by the plant (more information is needed and you should consult a health professional before trying to use it medicinally) and it is traditionally used in alternative medicine in its native countries.

This species needs to be grown in soil that is acidic. You can create new plants through seed germination. The new tree will be ready for foliage use in a few years. In practice, each plant is only harvested every other year so that it retains enough leaves for proper growth.

Scientific Name: Ilex paraguariensis
Other Common Names: Paraguay tea, South American holly, Brazilian tea, Jesuit tea, St. Bartholemew's tea, mate
Native to: Argentina, Brazil, Paraguay and Uruguay
USDA Zones: 9-11
