Gardeners' Notes:


On Aug 31, 2013, Phellos from Port Vincent, LA wrote:

We had one for almost ten years. From a seedling, it grew to ten feet tall with a dense six inch diameter trunk with very hard wood. It was planted against a wire fence beneath an oak tree and grew sideways into the neighbor's yard. The butterflies used to love the sweet fragrant yellow flowers. It was killed by a hurricane and now, almost another ten years later, the old dead trunk is still standing, almost solid!

This tree was given to me as shrub. I planted it in my front yard and it has grown four times its original size in half a year! With its' substantial growth, I was able to trim it into a tree. Very ornamental and pretty much the only deciduous tree in my yard. It has been in bloom for the past 2 months and now has several 6" seed pods growing on it. With the growth that this tree has shown, in two years, it will shade my sidewalk and the street! This tree also has very hard wood.

This should be under Acacia farnesiana. It is native to tropical and subtropical areas in the Americas, including much of the most Southern U.S. It may be native to other tropical and subtropical areas around the world.

It's native to Central and Southern Florida. The flowers are very sweet smelling hence the name, they appear in late winter and appear after every flush of new growth providing almost year round blooms. It has pretty fern-like foliage. It drops its leaves during drought in order to save water. It needs no irrigation once established. However it grows very slowly and has sharp thorns. Very attractive tree!

It has treacherous thorns, but the flowers are as sweet as any perfume. It prefers to grow on sandy soil and is salt tolerant.
