SA Census:
Census of South Australian plants (external link)     [genus Frankenia]
Name derivation:
Frankenia named after Johan Frankenius (1590-1661), a Swedish botanist. Serpyllifolia means having leaves like the species Thymus serpyllum (creeping thyme).
Distribution:
Found scattered across South Australia, growing on the edge of salt lakes and salty depression. Also found in the Northern Territory, Queensland, New South Wales and Victoria. 
Status:
Native. Common in South Australia. Rare in Victoria. Common in the other states.
Plant description:
Low, densely branched sprawling to erect shrub with branches sparsely to densely covered in hairs to 0.5 or more, internodes to 32 mm long. Leaves on long-shoot to 13 mm long with petiole to 2.7 mm long, tapered distally to 1.2 mm wide, ciliate. Leaf-blade elliptic, oblong, obovate or ovate, to 8 mm wide, flat or with margins loosely to tightly revolute, midrib inconspicuous or prominent, linear to flat, surfaces greyish yellow-green, glabrous to densely covered in hairs, short-shoot leaves similar. Flowers 1–19 in terminal or axillary clusters or solitary. Calyx 5-lobed, to 10 mm long and 2 mm wide, glabrous to densely hairy, petals to 15 mm long, stamens 6, style-branches 2 or 3, ovules usually 2 or 3. Flowers throughout the year.
Fruit type:
Brown cylindrical capsule.
Seed type:
Light brown, ovoid seed to 2 mm long and 1 mm wide.
Embryo type:
Spatulate fully developed.
Seed collecting:
Look at the tip of branches for dried flower heads. Collect the heads that are cylindrical, brown, slightly fat at the base. This should contain small ovoid seed.
Seed cleaning:
Place the flower heads in a tray and leave to dry for at least a week. Then rub the dried heads gently to dislodge the seeds. Use a fine sieve to separate the seeds from 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:
Seed set can be low but viability is high.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
