forms have blue, violet, rose, and 



white flowers blooming continuously 



from spring to fall in the North. All 



the species are more or less climbing 



in habit ; they show this especially 



in the extreme South where they are 



hardy. The fruit is a thin-coated one-seeded pod. The one species in 



most general cultivation has azure-blue flowers, except in the white 



variety, and blunt-tipped tapering-based leaves. Cape Plumbago (457) —

flowers, from South Asia, Uosy Plumbago (458) — Plumbago rosfea, — has 



larger leaves somewhat clasping at base. [Twig cuttings.]
