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 produces 3 to 4 inch seedpods in the fall. It is easy to grow, requires a sunny location in well drained soil and is very drought tolerant. In addition, it is a host to butterfly caterpillars. This plant would make a lovely addition to any landscape, especially wildscapes and xeriscapes.

For more information, see its entry in the PlantFiles:

It is literally covered with blooms. This photo does not do the plant justice, but at least it provides an image of its growth habit.
