I would like info on this tree. I have never seen anything like it. The tree has long
thorns on the trunk. This tree was spotted during a walk along Hot Springs Creek in
Hot Springs Thanks
Wow, that is a lot of thorns for even a honey locust tree! The tree in question is
the native honey locust tree – Gleditsia triacanthos. It has thorns on the trunk
and the branches and they can be deadly. The thorns grow from three to eight inches
long and are often produced in clusters on the trunk. It is not recommended for home
landscapes for an obvious reason. A thornless cultivar is on the market and does
have great yellow fall color, without thorns. In the past, the thorns have been used
for nails, fish hooks, sewing needles and more, but use extreme caution trying to
use them—they are sharp and tough..
I am hoping you can identify a tree by description without a picture. This tree has
thorns on the truck and branches. We saw this in the wooded area just as you cross
over the Two Rivers Bridge over the Arkansas River. I have never seen a tree of this
size with thorns.
My guess would be a honey locust - Gleditsia triacanthos. They have compound leaves with a lot of small leaflets on them, and the trunk and
branches can have some deadly thorns. They can form a large shade tree, but the thorniness
is the reason most home gardeners don’t want them in their yard. Plant breeders have
bred a thornless variety which has good fall color and makes a good yard tree. A smaller
tree that is native, and is covered in thorns is the Devil’s Walkingstick – Aralia spinosa.
