Common name: Cushion Bush
Origin of Scientific Name
Leucophyta: (Greek) from leuco – grey-white, and phyta – plant; referring to the plants colour.
brownii: named after the 18th to 19th century botanist Robert Brown.
Leucophyta brownii is a compact coastal shrub, widespread along the south-west coast of WA from Yanchep to the islands east of Esperance. This dome-shaped plant is found on limestone cliffs and primary dunes often in highly exposed areas where it can grow up to 1 m in height and width.
The most distinctive attribute of the Cushion Bush is its silvery-white foliage, which provides a dramatic contrast to surrounding vegetation. It has an intricate network of dense tangled stems with small scale-like leaves covered in soft white hairs.
From late spring to summer, Cushion Bush produces tiny yellow, tubular flowers, grouped in globular heads that have a creamy felted appearance. The heads appear silver when budding and grey-brown when fruiting.
The species is very popular as a landscaping plant especially in coastal gardens, grown primarily for its dramatic colour contrast against other plants, as well as its drought tolerance, reliable growth and compact dome-shaped habit. A wide variety of forms are commercially available including the dwarf variety ‘Silver Nugget’ and the very silvery ‘Canal Rocks’.
- Easily grown from tip cuttings taken anytime of the year from semi-hardened branches, but will also grow from seed with no pre-sowing treatment required.
- For best results plant in full sun in autumn or winter.
- Cushion Bush should not be over-watered once established as this will shorten its lifespan.
- Tip-prune regularly to shape as this plant does not respond well to harsh pruning into woody material.
- Cushion Bush is extremely tolerant to salt spray, wind and drought once established.
