I grew plants in Tallahassee, FL from seed collected near the Chipola river in Marianna (Jackson County) FL. They are slow-growing, but have very attractive form, and the flowers are of a dark purple color you rarely see. This is one of the few natives I have grown from seed that really works well as an ornamental. Mine are full of Silver-Spotted Skipper caterpillars, which make shelters from the leaflets, and come out at night to feed.

A good DG friend gave me one of these plants last year and I loved it so much I bought several more. I knew they were a host plant for Southern Dogface and Silver-spotted Skipper butterflies. Happily, I was able to raise a brood of the Skippers. Hopefully will get the Dogface this year.
The blooms are beginning to emerge now in early April and they are so amazing to watch developing! I get the name of them now A-MORPH-a... fruiticosa. Just as fascinating as the butterflies they support.

I grew these trees from seeds that a friend gave me. They germinated easily, but have been fairly slow growing. I have some of the trees in sun and some in shade. Those in sun are tallest, but still only about 6 ft tall after about 3 years of growth. I prune them regularly to keep them into a compact shape. They have a nice, light, "feathery" leaf structure, somewhat similar to a Mimosa or Cassia in leaf shape and position. The flowers are similar to Bottle Brush (Callistemon) flowers, but greatly reduced in size. The color combination of the flowers, very dark purple with a pin head sized tip of nearly fluorescent orange, is very striking!
