Etymology

Lobelia, named after Mathias de Lobel (1538-1616), physician to William of Orange and then botanist to James I of England. Anceps from the Latin 'anceps', meaning two-edged, referring to the two-lipped character of the flowers.

Plant description

Decumbent to ascending, glabrous perennial herb; rooting at nodes, with upper stems usually narrowly winged, often maroon-tinged. Leaves oblanceolate or obovate-spathulate to linear-elliptic, to 85 mm long and 20 mm wide; toothed or some entire, reducing toward inflorescence. Flowers bisexual, in terminal spike with light blue to violet (rarely almost white) flowers; 2 petals above and 3 below. Flowering between November and April. Fruits are brown cylindrical to conical capsule, slightly compressed, to 15 mm long. Seeds are orange to brown, slightly compressed, elliptical seed to 0.4 mm long and 0.3 mm wide; surface smooth or very faintly striated. Seed embryo type is linear, under-developed.

Seed collection and propagation

Collect seeds between December and May. Collect mature capsules that are fat, turning a pale straw-colour and containing brown seeds. Place the capsules in a tray and leave to dry for one week. Then rub the capsules gently by hand 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%.
