It doesn't get any better than this!
Very dense, super compact growth habit to 30cm tall and 70cm wide, grey-green leaves and masses of white flowers during spring. Spot flowers in summer and autumn. Pretty much "no maintenance".
Full sun, morning sun, afternoon sun. Heat, wind and frost hardy in Canberra and surrounding area's conditions.
Prefers well drained soil, will tolerate heavier soils once established.
