[3] It is a recently (2008) discovered shrub, often with many stems arising from a lignotuber and is similar to Melaleuca paludicola but has pink or mauve flowers tipped with yellow anthers over a short period between October and early December.

Melaleuca wimmerensis is a shrub growing to 10 m (30 ft) tall, often multistemmed with a dense crown and fibrous, grey to brown bark.

Flowering occurs over a short period between October and December and is followed by fruit which are woody capsules, 4.5–5.0 mm (0.18–0.20 in) long when mature.

[4][5] Callistemon wimmerensis was first formally described in 2008 by Neil Marriott and Geoffrey Carr in Muelleria, based on a population occurring on crown land on the west bank of the Mackenzie River near Horsham.

[10] This melaleuca occurs in the Wimmera district in Victoria growing in woodland near rivers and streams.
