Gymnocalycium baldianum hybrid (100 seeds)
Family: Cactaceae
Native to Argentina. Flat to globose depressed, up to 13 cm in width, greyish-brown to blue-green (rather variable in color in cultivation, and in some specimens it is almost blue-black). The 9 to 10 broad ribs are divided by deep grooves into tubercles.
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.
