The name Streptocarpus comes from the Greek for twisted fruit, a nod to the spiral seed capsules that set this genus apart from nearly everything else on a windowsill. Native to warm, moist highland environments across central and southern Africa, Madagascar, and pockets of Southeast Asia, these plants evolved in the dappled shade of mountain forests, which explains their indifference to direct sun and their appetite for consistent moisture without waterlogging.

Most grow in a compact basal rosette no taller than a foot, though trailing varieties push farther. They bloom prolifically in shades of violet, red, pink, and white, often with contrasting veining inside the throat. Deadhead each spent stalk at the base to encourage a continuous procession of new flower stalks. In summer, move potted specimens outdoors to a shaded patio; bring them back before any hint of frost, as they are tender below Zone 10.
