Detailed description
Self-heal is a low-growing, spreading by rooting at nodes; a perennial of the mint family. It has distinctive puckered leaves with an opposite arrangement on square stems. The ovate leaves (wider at the base and tapering toward the apex) are covered with short, coarse hairs. When viewing this plant from directly above, each set of leaves is rotated ninety degrees from the previous set.
Habitat
Because of its low growth habit, self-heal all can often escape detection until firmly established in the lawn. The first signs of of the plant are during flowering when hundreds of purple (occasionally mauve) flowers on short compact spikes are seen above the ground.

Wetland plant indicator status rating
Information derived from the revised national wetland plant list prepared to assist councils in delineating and monitoring wetlands (Clarkson et al., 2021 Manaaki Whenua – Landcare Research Contract Report LC3975 for Hawke’s Bay Regional Council). The national plant list categorises plants by the extent to which they are found in wetlands and not ‘drylands’. The indicator status ratings are OBL (obligate wetland), FACW (facultative wetland), FAC (facultative), FACU (facultative upland), and UPL (obligate upland).

FACU: Facultative Upland
Occasionally is a hydrophyte but usually occurs in uplands (non-wetlands).
