Family: Cactaceae
Common names: Bishop’s Cap, Bishop’s Miter, Bishop’s hat, Miter Cactus, Monk’s Hood.
Native to Mexico. Astrophytum coahuilense with five ribs, has a surprising similarity to Astrophytum myriostigma. However, it is different in all characteristics regarding flower, fruit, seed and embryo which looks like in all details to Astrophytum capricorne.
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. https://trexplants.com/blog/care-diary-how-to-grow-astrophytum-asterias
