Mazus pumilio, Swamp Mazus, is a member of the Mazacaeae family. The genus was previously included in the Scrophlurariaceae family.
Swamp Mazus is a low, perennial plant with leafy rosettes that are connected by rhizomes. The leaves are spoon-shaped and up to five centimetres long. Leaf margins may be toothed or entire, often with a wavy surface.
The lobed flowers are purple or white, about 1.5 centimetres long with two humps on the lower petal that almost close the throat of the bloom. They are held erect above the foliage on slender stems. The main flowering period extends from September to March with sporadic flowering at other times.
The Swamp Mazus occurs along the east coast of NSW as well as Queensland, Victoria and Tasmania with restricted distribution in South Australia.
Mazus pumilio given the right conditions, moist to wet soils, will form dense, colourful, ground covering carpets.
Propagate by rhizome division.
The species name means dwarf or pygmy.
