Avonia quinaria subs. alstonii is a dwarf perennial caudiciform succulent plant with a large, turnip-shaped rootstock buried to its rim, surmounted with myriads of silvery white stems, flush with the ground. The rootstock (caudex) is turnip-shaped with a spherical crown, above ground, flattened above, up to 3 inches (7.5 cm) in diameter. Branches are very numerous radiating from rootstock, up to 0.08 inch (2 mm) thick and up to 1.2 inch (3 cm) long. Leaves are very small, semi-orbicular flattish, completely hidden by the stipules. Flowers are usually white or in shades of pink, solitary, up to 1.2 inches (3 cm) in diameter.
Although regarded as a choice and difficult plant, in cultivation it is relatively easy. Avonia grow very slowly and requires careful cultivation. Clustering in cultivation, if grown correctly, it will reward the grower with generous displays of tiny flowers. Avonia grow well at moderate to cooler temperatures in partial sun. Bright light enhances leaf colors and makes for a compact plant. They enjoy a gritty free-draining soil with added organic material and low to moderate watering depending on the species.
A collection of these plants can be housed in quite a small space. Seed that germinate at 59°F to 70°F (15°C to 21°C). The seeds germinate very quickly. In cultivation the young Avonia plants develop much quicker than in their natural surroundings, where they don’t get ample water supply. Generally they are not easy to raise from seed as too much water kills them immediately, which also happens when they are not watered at all
