Angelonia angustifolia, commonly called Angelonia or summer snapdragon, is native to Mexico and the West Indies. It is an upright, glabrous, somewhat bushy, tropical perennial that is noted for its long summer bloom of small snapdragon-like flowers. Plants typically grow 12-18” tall. Stems are clad with narrow, oblong to lanceolate, green leaves (to 3” long) with toothed margins. Foliage is slightly aromatic. Bluish-purple flowers (each to 3/4” across) bloom from late spring to early fall in narrow terminal spikes (to 8” long). The two-lipped flowers are somewhat reminiscent of snapdragon. Cultivars are available in white, blue, light pink and bicolor flower colors.
