Impatiens walleriana Hook.f. (syn. Impatiens sultani Hook.f.) also known as Busy Lizzie, Balsam or simply Impatiens, is native to eastern Africa from Tanzania to Mozambique. It is a herbaceous perennial plant growing to 15-60 cm tall, with broa lanceolate leaves 3-12 cm long and 2-5 cm broad. Leaves are mostly alternate, although they may be opposite near the top of the plant. The flowers are profusely borne, 2-5 cm diameter, with five petals and a 1 cm spur. The seedpod explodes when ripe in the same manner as other Impatiens species, an evolutionary adaptation for seed dispersal.
