Plant description

Perennial herb to 80cm tall. Leaves alternating up the stems or sometimes the lowermost leaves opposite each other, to 6 cm long and 4mm wide, linear or the lowermost leaves flat, lower leaves hairy, upper leaves hairless, margins flat or wavy, entire or toothed. Flowers terminal, blue, funnel-shaped with 5 overlaying lobes. Flowers most of the year. Fruits are brown capsule. Seeds are tiny orange-brown 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 brown with brown 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 one collection, the seed viability was high, at 100%.
