Gardening for fun and wildlife at the edge of Houston’s piney woods

Yaupon holly ( Ilex vomitoria )

April 2nd, 2007

When we first moved here I went crazy trying to figure out what on earth all this stubby trees were in our yard. They are so common down here the gardening books ignore them.

They are a softwood small tree, best grown in clumps. Yaupon can reach 25′ in height. Usually the bottom 6′-10′ of branches are removed to give it a more tree like shape.

It’ll pretty much grow under any conditions forming thick, dense thickets if left alone.

The female trees have bright red berries, and it is ever green so it adds nice color to your garden around the winter holidays. The birds will feed on the berries late winter when other food sources are scarce.  The berries appear around Christmas, just in time to decorate your garden red and green for the holiday.

Tiny white flowers appear in the spring, but are not especially noticeable.  When the flowers fall there are so many it appears to be snowing for a few days in the back gardens.
It is not spider mites but bark lice that make those  ghostly webs on the trees. They do not harm the tree in any way. They eat fungus and other things off the bark and basically clean the bark on the tree. After a few weeks they will disappear along with the web. They appear most often in humid hot weather. So if you see them feel free to just leave them be, they’ll move on after cleaning your tree.

The leaves of yaupon are very high in caffine and were used in a purgatory tea by the native American Indians.

While there are some yellow berried varieties, I’m told they don’t always remain yellow berried.

    No problems with this plant and cold, at least as far as high 20s. No problems after the ice storm last winter either.

    I find the lower branches on this tree die back and need to be trimmed frequently to keep it looking nice.

    I also have to trim it away from the house twice a year.

    If it’s not near a home, it should be pain free other than knocking off the dead limbs at the bottom once a year.
