Aeschynanthus evrardii is a very large-growing plant, with spectacular clusters of brilliant orange and yellow flowers emerging from the stem tips. The general habit is upright and spreading, and the stems are very stiff and strong. Leaves are heavily succulent and leathery. Bloom clusters may emerge repeatedly from the same spur-like growth, in a manner not unlike some Hoyas.
The plant depicted here won a best in class award at the 1994 convention of the American Gloxinia and Gesneriad Society, in Toronto. It had been grown indoors in a large east-facing picture window up to the time of the show, because it is difficult to maintain show-level grooming on a plant grown outdoors. However, A. evrardii does best outdoors in full or partial sun from late spring to early fall. It will tolerate quite cool spring and fall temperatures, although this is problematic in the spring if the plant is accustomed to warm indoor conditions.
A close-up photo of the flower is available, as is one showing the splitting seed pods of this cultivar.
A. 'Hot Flash' is a hybrid of evrardii and A. hildebrandii.
