Name derivation:
Wahlenbergia named by H.A Schrader in honour of Georg Göran Wahlenberg (1780-1851), a Swedish professor of botany. Multicaulis from the Latin 'multus' meaning many and the Greek 'caulis' meaning stem.
Distribution:
Found in the higher rainfall regions in South Australia including the Mount Lofty Ranges, Kangaroo Island and the lower South-east, growing in grassy sites in various types of vegetation. Also found in Western Australia, New South Wales, Victoria and Tasmania.
Status:
Native. Uncommon in South Australia. Common in the other states.
Plant description:
Perennial tufted herbs with a fleshy rootstock. Stems to 75 cm long, branching below the flower-spikes. Leaves alternate or sometimes the lowermost opposite to 115 mm long and 10 mm wide, linear throughout or the lowermost oblanceolate, margins flat. Flowers blue, funnel-shaped with 5 lobes. Flowering between September and May.
Fruit type:
Pale brown elongated oblong capsule to 12.5 mm long.
Seed type:
Tiny brown elliptic seed to 1 mm long and 0.3 mm wide.
Embryo type:
Spatulate under-developed.
Seed collecting:
Collect capsules that are maturing, drying and turning brown with brown seeds inside.
Seed cleaning:
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.
Seed viability:
From one collection, the seed viability was high, at 80%.
