Ferdinand von Mueller Baron Sir Ferdinand Jacob Heinrich von Mueller, (german: Müller; 30 June 1825 – 10 October 1896) was a German-Australian physician, geographer, and most notably, a botanist. He was appointed government botanist for the then colony of Vict ...

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.
