Inflorescence a branching, flattish, rounded cluster of corymbs up to 8 in. wide.

Native of E. Mexico from Tamaulipas to Chiapas; and of Guatemala and Costa Rica. In gardens, where it is better known under one or other of the synonyms given above, it is most commonly grown as a pot plant, with greenhouse protection except during the summer. It is, however, hardy enough to be grown outdoors in the mildest parts; a plant at Logan in Wigtownshire has attained a height of 8 ft and a spread of 12 ft. A 6 ft plant at Belhaven House, E. Lothian, flowers throughout the winter and stood 120 of frost.
