Verticordia sieberi is a flowering plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia.

It is a shrub with one main stem, often compact but sometimes openly branched and with pink to pale purple flowers in summer and autumn.

It occurs along the south coast of Western Australia and inland near Frank Hann National Park and between Hyden and Lake King[2] in the Esperance Plains, Jarrah Forest, Coolgardie, and Mallee biogeographic region.

[9] Verticordia sieberi var pachyphylla is classified as "Priority One" by the Western Australian Government Department of Parks and Wildlife,[10] meaning that it is known from only one or a few locations which are potentially at risk.

All the varieties of V. sieberi have proven difficult to propagate and establish in gardens and success in growing the species is rare.
