Census of South Australian plants (external link)     [genus Wahlenbergia]
Name derivation:
Wahlenbergia named by H.A Schrader in honour of Georg Göran Wahlenberg (1780-1851), a Swedish professor of botany. Luteola from Latin meaning yellowish; referring to the yellowish outer colour of the flowers.
Distribution:
Found in the southern part of South Australia, from the Gammon Ranges to the lower South-east, growing on fertile, often clayey soils derived in lowland grassland and open woodland communities. Also found in New South Wales and Victoria.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Erect perennial herb to 60 cm high with thickened taproot and few to many stems from the base, freely branched, hairless or with short hairs near the base, usually leafy for the greater part. Leaves opposite throughout or becoming alternate above base, linear (or the lowermost narrowly elliptic or oblanceolate), to 60 mm long and 4 mm wide, margins entire or with a few small callus-teeth. Flowers terminal, blue, whitish or often yellowish outside, funnel-shaped with 5 narrow-triangular lobes. Flowering between October and March.
Fruit type:
Brown narrow conical capsule to 12 mm long and 3.5 mm wide.
Embryo type:
Spatulate under-developed.
Seed collecting:
Collect capsules that are maturing, drying and turning brown with hard 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 two collections, the seed viability were average to high, ranging from 75% to 80%.
