Crassula sieberiana

Australian stonecrop

Australian stonecrop is a small, erect or sprawling annual or short-lived perennial, with stems up to about 20 cm, narrow fleshy leaves 4–10 mm long and tiny four-parted flowers from pale yellow to red. It is widespread across Australia, New Zealand and Lord Howe Island, usually in rock crevices and thin soil, from arid inland ranges to wet coastal sites. Grow it as a small sunny rock-garden succulent in gritty mix, and expect it to seed around and behave partly as an annual.

Where it grows wild

It typically grows in rock crevices and shallow soil over rock, in places as different as arid inland country such as Sturt National Park and moist coastal sites near rainforest.

No elevation data were found. Its wide range suggests it grows from near sea level up to montane rock outcrops.
