Diplacus aurantiacus syn Erythranthe aurantiacus
Diplacus aurantiacus syn Erythranthe aurantiacus, Diplacus glutinosus
Common Names: sticky monkey-flower, orange bush monkey-flower.
This is an attractive summer flowering small shrub that loves warm places with good garden soil.
However botanically it is a horticulturist’s nightmare at present. Originally known as Mimulus aurantiacus, it was then changed to Diplacus and now is referred to as Erythranthe aurantiacus. That’s not the end of the story botanists are undecided if it should be a subgroup inside this genus with the section name Diplacus as these plants are woody shrubs where as other Erythranthe species are herbaceous. There is considerable disagreement about how to treat Diplacus. Kew Gardens currently list the name Diplacus glutinosus as an unresolved name. It will be some time until this happens and until then we should use the generic name Diplacus.
It grows naturally in southwestern USA from Oregon to California where it grows up to about 1m tall with 50mm long, narrow deep green sticky leaves.
The flowers are tubular and produce nectar to be collected by honey bees or hummingbirds which also pollinate the flowers enabling them to produce seed. The flowers are about 4mm long with a trumpet shape and may be a yellow orange or a deep red with a yellow throat. There is likely to be variation in flower colour and size when grown from seed.
The shrubs available though nurseries in NZ are generally cutting propagated one being yellow orange/apricot coloured and the other crimson scarlet with yellow throat (possibly called ‘Mrs Scholes’).
In summer they make rapid growth producing long stems with flowers protruding from almost every leaf axil. To keep this lush growth prune heavily in late spring to generate new vigorous growth.
Propagate from cuttings.
