Wine-red brush flowers appear for most of the year, heaviest from late winter into spring, over bronze-red new foliage.

Tubes suit a groundcover well, because each plant spreads so far that you need fewer than you might think. Expect a small plant on arrival that starts to spread once it has settled in warm weather.\u003c\/p\u003e\n\n\u003cp\u003eTube stock comes from our grower and is not always available. When the grower has none, the tube shows as sold out, and the notify button on the page emails you the day it is back.\u003c\/p\u003e\n\n\u003cp\u003ePlants are delivered Australia wide, with delivery from $29.95.
