Mine is a tree about 12' tall. It was here when we bought the house. It is planted in the ground in a planter surrounded by a concrete patio. It faces the east with lots of full sun until about 2:00pm in the summer time. It has produced yellow flowering blooms for months now with no signs of stopping.
The tree had been neglected for many months & we thought it was dead...just needed some water to bring it back to life. Will need to do some pruning to get it into a nice shape, but so far I love this tree with its profuse yellow flowers that birds, humming birds & butterflies love!
Does anyone know how to plant from the seed pods it produces? Would love to plant another one somewhere else.

I run a ranch for people with special needs (Down syndrome, etc.) east of Austin and bought a potted plant in spring 2005, planted it on an east/southeast side of a house. It took over, getting easily 7' tall with mounds of blooms.
I've got a bunch of seed pods from last falls flowers. The beany pod is dry on the outside but the inside seeds don't seem thoroughly dry. Anybody with experience propogating? We have greenhouses and may be interested in growing some. Always looking for good products that will do well in our Central Texas environment.

Bought this tree in a pot at a Louisiana open air market. Moved it to Texas, planted it on the West side of our house, and it has done great. Dies back each year, then grows to over 5 feet with luscious flowers and foliage in the fall. Breathtaking and very low maintenance. Curiously, we haven't had the seed pods...which is unfortunate because everyone that sees this beauty wants it.

Senna corymbosa, a native of Argentina, Brazil and Uruguay, has attractive, pinnate, deep green leaves with huge clusters of rich buttercup yellow (yellow-gold) 1 inch or so blooms. It is a naturalized species in parts of the southern U.S. It is easy to grow and requires a sunny location and well drained soil. It produces 3 to 4 inch seedpods in the fall. In addition, it is a host to butterfly caterpillars. This plant would make a lovely addition to any landscape.

I grow this plant from seed since last year. It has bloomed for me that first year even it was only a 12 cm plant! It is now out in the garden since this last spring and it has bloomed again for me at the end of summer. Though we had a little nightfrost it kept blooming. I don't know if it'll survive our winter because our winters are very unpredictable lately. I've planted them at very sheltered places and I'll cross my fingers. I live in the very south of The Netherlands in a zone 8a.
