A perennial herb, it has four-sided, densely hairy stems, narrow egg-shaped leaves, and white flowers usually arranged singly in leaf axils.

It is a root suckering plant, meaning that it spreads by pushing up new shoots around the perimeter of its original base.

Due to this root suckering ability, it is not uncommon for the Teucrium racemosum to spread to a diameter of several metres.

The flowers are usually arranged singly in leaf axils near the ends of branches on a pedicel that is 5–18 mm (0.20–0.71 in) long.

[2][3][4][5][6] Teucrium racemosum was first described in 1810 by Scottish botanist Robert Brown in his Prodromus Florae Novae Hollandiae.

[12] Gynodioecy occurs as a consequence of genetic mutation that prevents a hermaphroditic plant from producing pollen, while keeping the female reproductive parts intact.
