Anacampseros retusa Poelln.
Retuse anacampseros
Anacampseros retusa is a compact succulent from Namaqualand and the Semi-arid Cape, recognised for the notably retuse (notched) apex of its leaves, giving it a very distinctive rounded appearance. Forms dense rosettes, green to grey-green. Popular in collections for its unusual form and ephemeral pink flowers.

Propagation Strategy
- 1 Sow shallowly on mineral substrate.
- 2 Keep at 22–25 °C under plastic cover.
- 3 Remove cover when germinated; reduce watering gradually.
Tolerates slightly more shade than other Anacampseros, ideal for east-facing windowsills.
Substrate too rich producing elongated leaves that lose the retuse apex.
Every 3–4 years
Once in spring, cactus fertilizer very diluted (25%)

"The retuse leaf apex of A. retusa is unique in the genus. It is thought to reduce the sun-exposed area at peak insolation, functioning as a passive thermoregulation mechanism."
