Synonym: Echinopsis denudata
Common Name: sea urchin cactus
Origin: Echinopsis subdenudata originates from Bolivia, South America – specifically Santa Cruz, Tarija, Chuquisaca, and perhaps Paraguay. The natural habitat includes grasslands, shrublands, and forests, 600-1,800 meters above sea level.
Description: The sea urchin cactus is a small green plant that resembles a sea urchin. Often, cacti are globular but become columnar as they age. Tiny spines are hidden within white felt areoles along 8-12 ribs, and may become larger in older cacti. In summer, funnel-shaped white flowers form at the end of long tubes, night-blooming and fragrant.
