Plant description

Perennial tufted herbs with a fleshy rootstock with many stems from base, usually branched, rarely simple, glabrous, or hirsute near base, erect, to 50 cm high, leafy throughout or only toward base. Leaves alternate, oblanceolate (near base) to linear, to 50 mm long and 6 mm wide, margins entire or with a few small callus-teeth, flat or undulate. Flowers terminal, blue often whitish outside, funnel-shaped with 5 narrow-triangular lobes. Flowers throughout the year. Fruits are brown ovoid capsule to 9 mm long and 5 mm wide. Seeds are tiny orange elliptic seed to 0.6 mm long and 0.3 mm wide. Seed embryo type is spatulate under-developed.

Seed collection and propagation

Collect seeds between January and December. Collect capsules that are maturing, drying and turning orange with hard seeds inside. Place the capsules in a tray and leave to dry for a week. Then rub the capsules gently with your hands to dislodge the seeds. Use a sieve to separate the unwanted material. Be careful as the seeds are very small. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. From three collections, the seed viability were high, ranging from 80% to 85%.
