Cryptostegia is a genus of
Description
Cryptostegia includes three species of slender, many-stemmed, woody, perennial
Cryptostegia are evergreen and are grown for their showy ornamental vines. They are vigorous and self-supporting and their vines sometimes attain a length of 15m. Leaves are ovate, opposite, glossy and dark green. They are 6–10 cm long and 3–5 cm wide. Clusters of large, showy, funnel-shaped flowers with 5 white to rose-pink or reddish-purple petals bloom in summer after the wet season. Seed pods are rigid 10–12 cm long and 3–4 cm wide, and grow in pairs at the end of a short stalk. The seeds are attached to a silky white floss. The plants grow rampantly in a favourable climate and are invasive in some areas. In Australia Cryptostegia grandiflora in particular has been declared a Weed of National Significance. It is regarded as one of the worst weeds in Australia because of its invasiveness, potential for spread, and economic and environmental impacts.[3]
In cultivation, the plants require a hot climate.
