Additional comments: Great small herbaceous annual for use in the hottest Phoenix summer gardens. There are a number of named cultivars having different flower colors. Most cultivars are patented and are thus not legally propagated except by the persons holding the patent. Patented cultivars include 'White Imperial' and 'White Mist' (both with white folwers), 'Dark Pink' (solid pink flowers), 'Purple' (purple flowers), and 'Deep Plum' (deep wine red flowers). Angelonia deserves much more attention that it has received to this point as a warm season bedding plant for hot Phoenix mesic gardens. It is good for cut flower arrangements too. There are about 30 species of angelonia native to the tropical and subtropical New World.
