About
Pentachondra pumila, also known as carpet heath, is a small alpine shrub in the epacris family (Ericaceae). It is commonly found in Australia and New Zealand in areas of high rainfall, being known for its small white flowers as well as its red, hollow fruit that grows on branch ends. It is distinguishable as a prostrate, mat-like shrub, growing in rocky or boggy alpine areas. The fruit is edible and is a food source for many species of bird.
How to grow it
P. pumila requires open, sunny positions in areas that are subject to mild winters (no less than -5 °C), and cool, moist summers. A high rainfall is required as it is intolerant to drought. It prefers a gritty, peaty soil and rocky ground for establishment.
Where it grows
P. pumila occurs in areas above the treeline in cushion bogs, open snow tussock grasslands, and herbfields in Australia (Tasmania, Victoria, and New South Wales) and New Zealand (North, South, and Stewart Island). It is widely distributed through both countries in the aforementioned states, though less so in the North Island of New Zealand and New South Wales in Australia. It frequently grows in exposed, rocky sites or in poorly drained, peaty areas, and is commonly found on the nests of ants (genus Ochetellus). It is often confused with Cyathodes dealbata, which is similar in appearance and growth habit, though can be distinguished by the glaucus veins on the underside of leaves, which is not evident on P. pumila.
