Taxonomy and naming

''Verticordia insignis'' was first formally described by Stephen Endlicher in 1837 and the description was published in ''

When Alex George reviewed the genus in 1991, he placed this species in subgenus ''Verticordia'', section ''Catocalypta'' along with '' V. roei'', '' V. apecta'', '' V. inclusa'', '' V. habrantha'', '' V. lehmannii'' and '' V. pritzelii''. In the same review, George described three subspecies of ''V. insignis'': * ''Verticordia insignis'' Endl. subsp. ''insignis'' has white sepals, a style long, petals long,

Use in horticulture

This verticordia has horticultural potential because of its flowers, described as "outstandingly beautiful, resembling miniature powder puffs". It has been propagated from cuttings but establishing them in the garden has been difficult.
