Avonia is a genus of around 14 accepted species in the family Portulacaceae. Avonia is a South African endemic genus. Most have scaly formations on their leaves. Generally they dont grow much taller than 8cm. Flowers appear in the summer months and may be white, pink or purple, opening during the heat of the day and closing again in the evening. Most Avonia species favour bright indirect light and rich, well-drained soil. The soil should be allowed to drain completely between watering and should be fortified with enrichments in the spring to encourage the plant to emerge fully from winter semi-dormancy. When grown in small pots their height can be controlled and they make interesting looking natural bonsai. They are closely related to Anacampseros and were previously included in that genus. Species in the Avonia genus are collected by succulent enthusiasts the world over. They are well suited to pot culture and grow just as well on windowsills if given sufficient ventilation.

Avonia ustulata previously known as Anacampseros ustulata and commonly known as Moerbossie or Kirriemoer in Afrikaans is a caudiciform that won’t grow much taller than 4cm tall. It consists of many thin stems. It was used by farmers for preparing yeast used in making yeast buns and also used in brewing of beer. They produce creamy white flowers during late summer. The little flowers have a potent sweet smell that is surprising for such a small bloom.
