This cute little sea urchin is a cactus native to Catamarca province in northern Argentina. It starts as a flattened globe and grows into a6-inch blue-green cylinder with up to 14 ribs that are spotted with tiny black spines that emerge from fuzzy white areoles. If you are lucky, one or two many-petaled yellow flowers will emerge on long stalks. The flower stalks and buds are covered in dense hairs and the outer petals are tipped with spines. This plant does not like to be touched! In its native habitat, this species is accustomed to long, hot, dry periods with occasional cloudbursts. It can take temperatures from 40 to 115 degrees Fahrenheit and needs full sun.
March - April, May - June
