Inland Austral Hollyhock
Malva, a Latin name for mallow, which may have come from the Greek 'malache' or 'malakos', meaning mallow. Weinmanniana named after Johannes Anton Weinmann (1782-1858), a German born Russian botanist and gardener. The association of his name with the species is not known.
Distribution and status
Found inland across South Australia, growing in heavy soils prone to inundation such as watercourses, run-on areas and depressions. Also found in all mainland States. Native. Common in South Australia. Uncommon in the Northern Territory and Queensland. Common in the other States.

Erect, usually short-lived perennial shrub to 2 m high with hairy branches, mostly arising along a main central stem. Leaves sub-entire to palmately divided with 5ï¿½9-lobes, the mid-lobe usually longer than others; to 8 cm long and wide, broadly cordate at base; yellow green; moderately to densely hairy, usually more densely hairy and paler beneath. Epicalyx not exceeding the calyx. Flowers pale pink (yellowish base) with pink-stripes. This species differs from the closely associated species, Malva preissiana principally in flower colour and relative density of hairs on the upper and lower leaf surfaces, with M. preissiana having white flowers and with both surfaces of the leaves equally hairy. Malva preissiana and M. weinmanniana can be distinguished from the hybrid, Malva arborea ï¿½ M. preissiana, which has epicalyx and calyx lobes of similar length, whereas the epicalyx lobes of the native taxa are shorter than those of the calyx. Flowering between July to February. Fruits are hairy pale brown capsule to 11 mm diameter with 12ï¿½15 seed segments. Seed embryo type is folded.
Seed collection and propagation
Collect seeds between September and April. Collect mature capsules that are turning pale straw coloured and contain dark hard seeds. Place the capsules in a tray and leave to dry for two weeks. Then rub the capsules gently with a rubber bung or by hand to dislodge the seeds. Use a sieve to separate the unwanted material. 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. This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
