Echinocactus are rounded cacti with prominent ribs and robust spines whose geometry gains presence through slow growth.
Echinocactus stand out for rounded forms, pronounced ribs and strong spines. Their geometric structure is appealing even in young plants, although some species can grow large over many years.
Growing them in pots lets you follow the gradual development of ribs and spines. Slow sun acclimatisation and a mix that does not retain excess water support firm growth. Explore Ferocactus.
