This cactus has vibrant orange-red flowers. The seed has been harvested from Prof Ralph Martins extensive collection.
Sow in a tray using well drained cactus potting compost, water. Cover the pot for germination. The seed will start to germinate in 2 - 3 weeks but may take much longer
Pot up when the seeds are large enough to handle in well drained cactus compost. Some seedlings will grow slowly so be patient before potting them all up.
