Alex George reviewed the genus ''Verticordia'' in 1991, he included this species, conserving the specific epithet ("like a verticordia").
George placed this species in ''

Use in horticulture
Although not having the horticultural potential of other verticordias, ''V. verticordina'' is relatively easy to propagate from
cuttings and can be grown in pots or hanging baskets but does not flower prolifically.
