Gardeners' Notes:

Love this bush. I let it grow wild up into the trees which takes up alot of room. The "thorn" is a backwards growing branch that grabs onto an upper branch of a taller tree. If you decide to trim the silverthorn into a hedge you'll have trouble getting the branches out of the tree. If you cut them in fall, by springtime they can be pulled out because they die and become brittle. These bushes saved us from any wind damage during the 2004 hurricanes and the cardinals nest in them and are very well protected. When I trim a branch it is only to get it to grow in another direction. I cut close to a leafbud that is facing the direction I want.

This is a very nice evergreen shrub. Actually, Silverthorn does not have thorns. This plant is highly drought tolerant and can grow really fast. It tolerates air pollution, salt spray, and poor soil. The fruits are edible. Landscape designers love to use this plant for screening purposes.
