Utricularia violacea

violet bladderwort

The violet bladderwort is a tiny annual terrestrial bladderwort of southern Australia's winter-wet swamps, seepages and granite outcrops. It germinates with the autumn and winter rains, flowers mostly from September to November, and dies as the ground dries in summer, surviving as seed. Growing it means recreating that one-season cycle in bright light on wet sand.

Where it grows wild

Herbarium labels describe damp to flooded grey sand, sandy peat and sandy clay in wet heath, paperbark swamps, winter-inundated claypans, road-side gutters, clay floors of quarries and wet soil pockets and moss mats on granite outcrops. It often grows with Stylidium, Drosera, Centrolepis and other small annual bladderworts, sometimes in a few centimetres of standing water, and it appears readily after fire.

Lowland: coastal plains and low inland granite country, mostly below about 400 m.
