Lechenaultia biloba

Lechenaultia biloba, pale blue
Common name: Blue Leschenaultia

Family: GOODENIACEAE (13 Genera)

Origin of Scientific Name

Lechenaultia - After Jean Baptiste Louis Claude Théodore Leschenault de la Tour (1773 - 1826). The genus is spelled without the ‘s', because Robert Brown, who named the plant, misspelled Leschenault's name. The common name however, is spelled with the 's'.

biloba - Latin = two-lobed, referring to the corolla lobes of the flowers.

Description

Small twiggy shrub to 30 cm, with intense, vivid blue flowers in its common form, though paler forms are known, as is a pure white form. Linear, narrow, mid green leaves. The flowers, at 20 to 30 mm are quite large considering the small size of the plant.

Distribution

Found solely in Western Australia, mainly on the Darling Range, but as far north as Geraldton and as far east as Lake King.

Flowering Season

July to December.

Cultivation/Propagation

The plant is not long-lived, three to four years being its most probable life span, but luckily, the species is easily propagated by cuttings, with most success in late spring and summer. Semi-hardened material 6 to 10 cm long gives the best results. In cultivation it is essential that the plant is grown in a sandy, well-drained situation. It prefers dry summers, so do not over-water. It is frost tolerant.
