About
Eremophila polyclada, commonly known as twiggy emu-bush, flowering lignum, lignum fuchsia and desert lignum is a plant in the figwort family Scrophulariaceae and is endemic to Australia. It is a dense, spreading shrub with narrow leaves and white to pale lilac-coloured, purple-spotted flowers. It occurs in all mainland states except Western Australia.
How to grow it
Twiggy emu-bush is an ornamental shrub which is well known in horticulture, and some specimens have been grown for more than 35 years. It flowers profusely in summer, bearing masses of white flowers when most other shrubs are dormant and is a useful screening plant, with its dense, tangled branches. Propagation is easiest from cuttings which strike within a few weeks in warm weather and its arching branches sometimes develop roots when they touch the ground. A very drought tolerant shrub, it only requires watering once or twice during a long drought and a deep watering early in summer will sometimes stimulate a mass flowering. It is also tolerant of frost and can be pruned, preferably in early autumn. A hybrid with E. divaricata called Eremophila 'summertime blue' is popular in American gardens.
Where it grows
Eremophila polyclada is widespread in New South Wales to the west of Lightning Ridge and in southern Queensland. It is also found in a few places along the Murray River in Victoria and South Australia. There is one record from Tarlton Downs in the Northern Territory. It grows in sandy to clay loam soils often on floodplains and other low-lying areas.
