Description
Mammillaria mammillaris. Fairly slow growing and usually solitary or forming clumps. The stem is globose to short cylindrical, light to dark green, shiny, 8 to 20 cm in diameter. With latex. Sowing : 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. Locality : Ex Hort. Date of harvest: September 2021
