About Hippeastrum striatum (Lam.) H.E.Moore
This species, Hippeastrum striatum (Lam.) H.E.Moore, typically produces 2 to 4 smaller flowers than most other members of the Hippeastrum genus. Its paraperigon has bristles located at the throat of the tepal tube. The overall perigone measures approximately 7.6 to 10 cm across, and the tepal segments are 2 to 2.5 cm wide at their midpoint. The flowers are bright red, with a green keel that runs halfway up each tepal segment. The stigma of this species is trifid. Hippeastrum striatum is native to Northeast, South, and Southeast Brazil, and has been introduced to the Caroline Islands and Hawaii. Ecologically, this plant produces numerous bulbils, which help it escape cultivation and become naturalized in tropical regions. When grown from seed, it reaches maturity in approximately two years.
