Crassula biplanata
A small, branching shrublet up to about 30 cm tall, with tiny grey-green lanceolate leaves on thin papillose stems. It grows on rocky ledges and stony mountain slopes from Franschhoek through the Little Karoo and Overberg to Humansdorp in South Africa's Cape. It needs full sun, a gritty, fast-draining mix and careful watering, and turns silvery and compact in strong light.
Where it grows wild
Shallow soil on rocky ledges, very rocky soil on lower mountain slopes and rock cracks higher up, in fynbos and succulent Karoo scrub. In exposed positions plants are smaller, often sprawling, and covered in a dense silvery wax.
No elevations are recorded on the wild records we checked; the habitat described (lower mountain slopes to higher rock cracks in the Cape Fold Mountains) suggests roughly 200-1,200 m.
