Why is it a pest?

  • Aluminium plant grows rapidly to cover large areas of ground with a thick mat that stops seedlings of other plants from establishing.

  • The leaves are hairy, pointed, coarsely toothed, and mint-like, in opposite pairs, with silvery-grey patches on the upper surface.
  • Stems are purplish, square and densely hairy on the angles.
  • From December to May tubular, hairy, lemon yellow flowers (20-25 mm long) are produced in dense axillary whorls, but no seed is set.
