s and 12–16 mm long. The plant flowers from autumn to winter, attracting bees and butterflies. ''Senna bicapsularis'' is distinguished from '' Senna pendula'' by having 3 pairs of leaflets on each leaf and elongated pedicels (flower stalks), while 'S. pendula' has 4-7 pairs of leaflets on each leaf and a gland between each pair of leaflets, with shorter flower stalks. S. bicapsularis flowers from late fall to winter depending on climate, whilst 'S. pendula' can flower from as early as late summer. Senna pendula can grow very easily from seed, while bicapsularis has a tough seed coat that needs mechanical scarification to sprout with success.
