In zone 9b/10a, Bradenton, FL. Tree is about 7 years old, flowers yearly, hardly have to do a thing to it. No problems with fungus or pests. Harvested seeds from the tree yesterday (3/24/3015) - not quite sure how to de-pod them, have never dealt with these seeds before.

Blooms as long as the weather is warm. Also attracts hummingbirds!
One of my favorite plants.

I got this plant in late summer last year. It was in bloom and bloomed until cold weather.

Now it is the first day of summer and it is in full bloom again. The colors are striking.
