All parts of the plant if ingested will cause severe stomach upset.

Botanic information
Leaf: The dark green linear leaves up to 20 mm (¾ in) wide with an acute apex and pinkish or reddish at the base. The upper surface is conspicuously nerved and the leaves tend to arch.

Flower: The flattish crateriform flowers have a perianth tube that is up to 25 mm (1 in) long with red-purple, lilac, white or cream lanceolate segments (petals) with darker veins. The oblanceolate to obovate falls (sepals) are up to 88 mm (3½ in) long. There are 2 to 3 flowers arranged on a branched stem up to 800 mm (31 in) tall above the foliage and appear from mid-spring to early summer.

Fruit: The small 3 to 6 angular leathery capsule contains numerous pitted seeds that are viable but the plant is commonly reproduced vegetatively to maintain true to type.
