It can grow to a height of 10 to 13 feet. Its light green foliage forms a medium to dense crown. Native to southern Europe, North Africa and the western Himalayas, this plant is said to be the only vegetation to be found growing in the crater of Vesuvius. Bladderpod will tolerate any well-drained soil; acid, neutral or alkaline, and actually thrives in nutritionally poor soils.  It prefers full sun, but will tolerate partial shade, and has low water needs. Drought tolerant once established, this adaptable shrub also tolerates pollution and is a good choice for an urban xeric garden. The extended flowering period and attractive pods make it a good ornamental shrub.
