Worsleya procera

About

Worsleya is a genus of Brazilian plants in the amaryllis family Amaryllidaceae, cultivated as an ornamental because of its showy, pale violet flowers, often with a yellow stripe down the middle of each tepal. There is only one known species, Worsleya procera, native to eastern Brazil. It is endemic to the mountains around Petrópolis, about 40–50 km (25–31 mi) north of Rio de Janeiro. Here the sickle-shaped leaves curve northward. When grown in the northern hemisphere, the leaves curve southward. It has one of the largest bulbs, around 1.5 m high by up to 30 cm (12 in) thick near the base) and also rarest members of the subfamily Amaryllidoideae.
