Marrubium vulgare

LOCATION: European native, naturalised through North America. An invasive pest plant that thrives in poor soil and drought conditions.

DESCRIPTION: Low growing plant with grey rough-surfaced leaves and tiny white flowers. Extremely drought tolerant. Scattered throughout the pasture areas and on a few open track sides elsewhere. It is technically a herb and crushed leaves have unpleasant smell. Seeds catch in sheep’s wool and plant is commonly found at sheep camps (at the end of ridges, on high points and saddles).

CONTROL: Isolated plants can usually be pulled when the soil is damp.
