Acanthocalycium chionanthum
Family: Cactaceae
Native to Argentina. The stem is spherical, over time it becomes slightly cylindrical, growing to a height of 12 cm or more, and a diameter of 6 to 10 cm. The epidermis is green to dark blue grey, and become a clear powdery-grey in the older part of the stem.
Sowing instructions: Fill a pot with a moist, gritty, loam-based compost, or cacti compost. Gently firm down and level the surface. Scatter your mixed cactus seeds over the surface, taking care not to sow them too thickly. Gently sprinkle a thin layer of vermiculite or fine grit over the seeds, covering the whole surface of the compost. Leave the pot in a greenhouse or on a warm windowsill, covered with a clear plastic bag to preserve soil moisture. Seedlings will develop within a few weeks. Remove the plastic bag and water when the compost becomes dry, but spray the surface with water regularly, to keep it moist.
