Turbinicarpus polaskii
Family: Cactaceae
Native to Mexico. It is a tiny slow growing solitary cactus with a flattened globose stem that is pale grey-green, olive green or purplish-tan in full sun, 2 cm tall, 3.5-5 cm in diameter.
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.
