Stems and Leaves

This species does not have any aboveground stems, except for the long flowering stalks. These are green, round in cross-section (i.e. terete) and hairless (i.e. glabrous). They are quite thick and have hollow centres.

The very large and strap-shaped (i.e. linear) leaves are produced in clusters (of up to 20 leaves) at the base of the plant (i.e. they are basal). These glossy leaves (20-70 cm long and 3-5 cm wide) are relatively thick and somewhat fleshy or leathery in nature, with veins running lengthwise (i.e. parrallel veins). They are stalkless (i.e. sessile), but have a short sheath at their bases. Their margins are entire and they are hairless (i.e. glabrous).

Flowers and Fruit

The flowering stems bear a single large, dense, and almost spherical cluster of numerous (i.e. up to 100) flowers at their tips(i.e. a terminal umbel). These flowers are initially enclosed in two thin leafy bracts, which are shed as the flowers begin to open. Each of the bright blue to mauve (or occasionally white) flowers is borne on a long spreading stalk (i.e. pedicel) 9-12 cm long. They have six large 'petals' (i.e. perianth segments or tepals) that are 40-45 mm long and 6-11 mm wide. These 'petals' are fused into a tube (15-20 mm long) at the base. The flowers also have six stamens, consisting of long filaments tipped with anthers that are yellow at first and become darker with age. These stamens surround a single long style that is tipped with a globular (i.e. capitate) stigma. Flowering occurs mostly during summer (i.e. from November to February).

The fruit is a relatively large and somewhat elongated three-sided capsule (about 50 mm long). These fruit turn from green to pale brown or straw-coloured as they mature, and split open to release their numerous (20-100) seeds. These seeds are black, flattened, and have a wing-like projection.
