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

Verticordia monadelpha is a dense, rounded shrub which varies in height between 1.7 and 2.0 m (6 and 7 ft) with many branches on a single main stem.

[1] Verticordia monadelpha was first formally described in 1847 Nicolai Turczaninow from a specimen collected by James Drummond, sometime in the 1840s.

It is restricted to an area north of Geraldton and south of the Emu Proof Fence, in the Kalbarri National Park and south-east toward Morawa.

[1][7][8] Verticordia monadelpha populations were once threatened by overexploitation for cut flowers, but are now protected by state's general prohibition of wildflower picking.

Variety callitricha is more desirable because of its mounds of bright, unusual colour but needs to be grown in positions of low humidity.
