The first scientific collection of verticordia specimens was made in 1791 and the first formal description of a verticordia was written in 1826 but the name ''Verticordia'' was not used until 1828.
Alex George undertook a revision of the genus and in 1991 published a paper describing three subgenera, 24 sections, and 102 species.

, often described in superlatives, which form massed displays in woodlands and heaths. These shrubs have appealed to amateur collectors and botanists, and were appreciated by the peoples of Australia before European settlement. The fringed or feathered appearance of the flowers is often enhanced by vivid and contrasting colours: this has given a common name for the genus, featherflower. The variety displayed within the species, and between species in the genera is highly diverse.

petals is highly diverse, it may be solid, or variable, or mutable.
These may be of several colours, or solid, the striking combinations are of all colours except blue. There is no unisexual flowers in the species.
Different species may be growing together, their massed displays creating painterly contrasts in flowering landscapes.
They are highly variable in appearance, often as a woody shrub, low or up to 2 metres, two tropical species are 7 metres. Branches may be upright or splayed out, sometimes pendulous, and are tightly or sparsely arranged. Leaves are very small or medium, scattered or opposite, and might be ciliated at the margin. The leaf shape is highly variable across, and these may differ at the base and floral leaves on individuals.
Hybrids of different species have been recorded and identified. A variant, known as 'Eric John', appears to be an intergeneric cross between ''V. plumosa'' and ''
Chamelaucium floriferum''.

In 2010, George described a new species, ''
V. setacea'' and new subspecies of ''
V. mitchelliana.
At present, the subgenera are
''Chrysoma'' with seven sections and twenty-one species, subgenus
''Verticordia'' with eleven sections and thirty-six species, and subgenus
''Eperephes'' with six sections and forty-four species.
Distribution and habitat
''Verticordia'' occur naturally in woodlands, sandy heaths and on granite outcrops. The mediterranean climate, sandy soils of the Southwest of the state, is where the greatest number of ''Verticordia'' species are found.
Use in horticulture
''Verticordia'' are known for their feather-like or fringed flowers, the beauty of these is invariably included in any description. This has been accompanied by a high desirability as a garden plant, and as a cut flower. Restrictions exist on the collection of wildflowers in Western Australia, but previous collection of flowers for the floral industry is thought to have placed some species under duress.
They are generally somewhat difficult to grow in cultivation, but some success has been achieved. The most reliable species is ''V. Plumosa'', the Plumed Featherflower, but many other species are found in highly specialised habitat.
Outside of their natural habitat ''Verticordia'' have shown consistently good results in the temperate regions of Australia. All species require excellent drainage and prefer Mediterranean-type climate of very dry summers and wet winters.
The cultivation of ''Verticordia'' in the Eastern states of Australia has proved difficult; many of the species are intolerant of the wet summers of those regions, especially with regard to root or collar rot and moulds and mildew. The successes achieved by some growers have been through the use of
