20 Echinocactus platyacanthus Seeds

Echinocactus platyacanthus Seeds

There are 10 species or less of Echinocactus coming from southwestern USA and northern Mexico. They are closely related to Ferocactus. They vary in size between small plants to giants 3 feet wide and 6 feet tall (1 by 2 m). Most species are subject to scarring at the base of the column, and this can be partially avoided by providing regular water and fertilizer. The name Echinocactus comes from the Greek for "hedgehog cactus", "cactus" being an alternate name for "thistle".

Echinocactus are easily propagated from seeds, and grow rapidly if they are given abundant water and fertilizer. They can be used for landscaping until after they reach 4 inches in diameter (10 cm), 1 to 2 years after being sown. Young Echinocactus should be protected from direct sunlight, until fully acclimated.
Most Echinocactus are fairly cold resistant, often to below 20°F (-7°C).
