Crassula colligata

A tiny erect annual Crassula, up to about 16 cm tall, from southern Australia (with records also from New Zealand). It grows in open, often rocky or sandy ground on cliffs, scarps, gullies, granite outcrops, behind dunes and near salt lakes. Like other small annual Crassula it grows through the cool, wet winter and dies as the soil dries, so you grow it from seed each year.

Where it grows wild

Wikipedia describes cliffs, scarps, gullies, dune hollows and the margins of salt lakes. Field observations on GBIF add exposed granite outcrops among moss and lichen, open native and exotic grassland, low coastal shrubland behind foredunes, post-fire mallee shrubland and open Eucalyptus woodland. All are open, sunny places that are damp in winter.

A lowland to low-hill plant: GBIF elevations run from about 100 to 850 m.
