Did you know

  • Cape primroses are close cousins of African violets—both belong to the Gesneriaceae family and originated in African forests, but the streptocarpus has trumpet-shaped rather than five-petaled flowers.
  • A single cape primrose plant can bloom continuously for 6 months or more indoors—it's one of the most floriferous houseplants in existence.
  • The botanical name 'Streptocarpus' means 'twisted fruit' in Greek—the seedpods spiral like corkscrews as they ripen and dry, eventually flinging their seeds outward.
  • Some cape primroses don't grow normal stems at all—instead, a single huge leaf produces flowers directly from its base, a botanical oddity unique to the genus.
  • Hybridizers in the UK and US have bred over 1,000 named varieties—the Dibley Nursery in Wales has been Britain's leading streptocarpus breeder for over 40 years.
