Genus guide
Echinocereus — 10 species
Part of the Cacti family (Cactaceae)
Echinocereus is a genus of ribbed, densely-spined cacti native to the deserts of the American Southwest and northern Mexico. The Claret Cup (E. triglochidiatus), Lace Cactus (E. reichenbachii), and Texas Rainbow Cactus are grown for their vivid spring flowers in red, magenta, and purple. They demand full sun — at least six hours daily — and sharply draining soil, with watering confined to the active growing season and near-dry conditions in winter. Toxicity is not uniform across the genus, so check individual species before buying if pets are present.

Echinocereus — frequently asked questions
Are Echinocereus plants toxic to cats and dogs?
Most Echinocereus are pet-safe. Of the 10 Echinocereus species we cover, 7 are non-toxic on the ASPCA list and 3 carry a toxic or mildly-toxic rating. Even so, confirm the individual species before trusting it around pets.
How much light do Echinocereus plants need?
Most Echinocereus do best in direct sun. If yours stretches toward the window or loses its variegation it wants more light; scorched or bleached leaves mean it is getting too much direct sun.
Are Echinocereus easy to care for?
Some Echinocereus suit more experienced growers — several want strong light, sharp drainage or a specific seasonal rhythm. Check the individual species page for the exact regime.
