Name derivation:
Cynoglossum from the Greek 'kynos' meaning a dog and 'glossa' meaning a tongue, alluding to the shape of the leaves. Suaveolens from the Latin ‘suave’ meaning sweet, alluding to the sweet-smelling fragrance of its flowers.
Found in the southern part of South Australia, growing in moist places in open-forests and woodlands. Also found in Queensland, New South Wales, Victoria and Tasmania.
Native. Common in South Australia. Common in the other States.
Plant description:
Perennials herb to 40 cm high with one to few erect stems from the basal rosette, with a tap root, covered with spreading to appressed hairs. Leaves densely clustered; oblanceolate, subpetiolate but with a broadened sheath in the basal rosette becoming widely spaced; lanceolate and sessile below the inflorescence to 15 cm long and  1.8 cm wide; pointed, often with undulate margins. Flower-spike terminal with pedicellate funnel-shaped, blue flowers. Flowering between September to January.
Fruit type:
Brown fruit cluster with upto four seeds hanging along fruiting spike.
Seed type:
Brown globose seed to 4 mm long and 4 mm wide covered in barbed spines to half of the surface.
Embryo type:
Spatulate fully developed.
Seed collecting:
Collect maturing fruits, those turning brown and contain a hard seed inside, by running your hands along the fruiting spike or break off the whole spike. Wear gloves as fruits can be prickly.
Seed cleaning:
Place the seeds/spikes in a tray and leave to dry for two weeks. No further cleaning is required if only seed collected. If seed spikes collected, use hand to strip off the mature seeds. 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 germination:
Seeds are non-dormant, viable seed should germinate readily.
