Seeds from this Cassia candolleana or Golden Senna. This plant stays evergreen and produced these gorgeous masses of bright yellow clumps of blossoms both in early spring and late fall unlike the Christmas Senna that only blossoms at Christmas. This plant is a very fast grower will not take too long to blossom from seeds. Another real show stopper for the neighbors. It grows 5 to 6 feet tall and 6 feet across and is hardy in zones 9-11. Drought tolerant and likes full sun but will tolerate part shade with fewer blooms.
