Bauhinia yunnanensis (Yunnan Bauhinia) - A tendril-bearing, semi-deciduous vine with 2 inch long, deeply cleft heart-shaped, light green leaves. The light lavender/rose-pink orchid-like flowers are five-petaled, of which the upper three are veined with deep purple red. Brown seed pods follow the spring through fall bloom. Once established this vine is somewhat tolerant to frost and drought, but looks better if planted in a warm, protected area and given regular watering. Spreads to 25'. Hardy and evergreen to about 20-25° F but planted as a deciduous vine in the southeastern US where it is considered hardy to below 10° F. This plant comes from the the Chinese provinces of Sichuan, Yunnan, and Guizhou where it grow up to 6,000' in elevation. The name " Bauhinia " was a name given this genus by Linnaeus to honor the twin brothers Johann and Gaspard Bauhin, who were 16th century Swiss scientists - Johann was a botanist and Gaspard a botanist and physician. Using the name of these identical twin is fitting as Bauhina leaves are composed of two identical lobes. The specific epithet references the area where this plant is native to. We have grown this plant since 1988 under the name Bauhinia corymbosa, so named in reference to the clusters of flowers, and this name has been erroneously and widely used for this plant in horticultural trades, while all evidence is that it is actually Bauhinia yunnanensis. The true Bauhinia corymbosa is a tender more tropical plant that likely could not be grown in California. It has clusters of fragrant small white flowers with pink stamens. It has also been offered at Bauhinia bohniana.
Information displayed on this page about Bauhinia yunnanensis is based on the research conducted about it in our library and from reliable online resources. We also note those observations we have made of this plant as it grows in the nursery's garden and in other gardens, as well how crops have performed in our nursery field. We will incorporate comments we receive from others, and welcome to hear from anyone who may have additional information, particularly if they share any cultural information that would aid others in growing it.
