Overview of the Yaupon Holly:
This small evergreen tree will add color to your garden throughout the year with its green leaves and red berries.
This member of the Aquifoliaceae (holly) family has been given the name of Ilex vomitoria. The species name vomitoria came about because of its use in Native American ceremonies that included vomiting.
There are many common names that you may see used for this tree. They are yaupon holly, yaupon, emetic holly, cassine, cassina, cassena, evergreen holly, evergreen cassena, Christmas berry or Indian blackdrink.
The word yaupon is taken from the word yopún, which comes from the Catawban language.
Preferred USDA Hardiness Zones:
The yaupon prefers to be planted in Zones 7-9. It originally comes from the southeastern United States.
Size & Shape of the Yaupon Holly:
This plant can either be a shrub or small tree based on growing conditions and the cultivar chosen. Heights can be anywhere from 4-30' tall.

Foliage/Flowers/Fruit of the Yaupon Holly:
The glossy green leaves are oval and up to one inch long, featuring fine-toothed margins. The tooths on the margin may be pointed or rounded.
Each plant produces little white male or female flowers in the spring, though only the females will bear fruit.
Little red berries appear on the female trees. Sometimes they may be yellow. They work well to add winter interest and provide food for birds.
Design Tips For the Yaupon Holly:
If you live near the ocean or other locations with higher levels of salt in the soil and air, this tree is a good choice since it will tolerate salinity well. It is also a drought tolerant tree if the roots are properly established.
Since these trees are dioecious, you will need at least one male and one female if you want the female to produce red berries.
Birds like to snack on the fruit so this is a welcome addition to any garden if you are into birding.
Growing Tips For the Yaupon Holly:
Acidic or neutral soil is needed by this plant for proper growth. It does best in sandy soils, but is able to handle other types also.
There is a possibility of suckers forming and causing new trees to grow. If you remove them, you may need to use a herbicide like glyphosate or they will keep coming back.
