- Description
-
Gloriosa superba is a slender, herbaceous vine grown from a thick tuberous rootstock. The leaves alternate or appear opposite and are, simple, strap-like with a tendril-like tip. The flowers grow on long stalks and are 6-parted, yellow or red with wavy margins. They should be planted on a trellis for support but stems can be damaged if handled too much to train them.
All parts are poisonous, especially tubers (thickened roots) which resemble yams. This plant is highly toxic and may be fatal if eaten.
