Coryphantha echinus
Family: Cactaceae
Common names: Prickly Beehive Cactus, Cory-cactus Edgehog, Sea Urchin Cactus
Native to Mexico. Spines largely obscuring the stem. 3 (0-4) central spines, 2.5 cm long; 16 to 30 radial spines, 1 to 1.8 cm long.
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.
