Graptophyllum spinigerum
Uncommon small to medium low growing compact shrub, to about 1.5 to 2m tall and 1.5 to 2m across, with  stems that grow in a layered fashion, giving an overall flat-topped appearance.

It has soft, dark green, glossy, diamond-shaped leaves, with irregularly toothed margins, which grow in pairs. Occasionally there are fine spines found in the leaf axils. A characteristic of this species is that each pair of leaves has one large leaf and one small one.

Small, white, tubular flowers with pink spots inside are produced in clusters in the leaf axils throughout the followed by brownish, woody, club-shaped capsules which split open when ripe and shed their seeds explosively.

Grows as an understorey plant in rainforests in south-eastern Queensland and further north near Coen and Cairns, I have had one growing in shade and one in full sun for the past 7 years.
The plant growing in full sun is now around 2m x 2m and more compact, it also flowers a lot better.

This is a tough plant which does not appear to be affected by frost or dry conditions.
Butterflies and bees love it and the Superb Wrens are nesting in it.
