Cape Primrose
Streptocarpus hybridus
Streptocarpus hybridus is a flowering houseplant that produces arching sprays of trumpet-shaped blooms — in white, purple, pink, blue, and red, often with beautifully veined or patterned throats — from velvety, elongated leaves that form a low rosette. Your plant can bloom for up to 10 months of the year given good indirect light, which makes it one of the more generous flowering houseplants around. It is closely related to the African violet and shares its easygoing temperament, making it accessible to most gardeners.

Fun Facts
The genus name Streptocarpus comes from the Greek words for 'twisted fruit' — a reference to the spirally coiled seed pods the plant produces after flowering. When ripe and dry, the pods unfurl in a helical fashion reminiscent of a narwhal's tusk.
