Echinopsis subdenudata Cárdenas
Accepted Scientific Name
Echinopsis ancistrophora Speg.
Domino Cactus, Easter Lily Cactus, Night Blooming Hedgehog
This species is native to Bolivia. It occurs mainly in grasslands, shrublands, and forests at elevations between 1,970 and 5,900 feet (600 and 1,800 m).
Echinopsis subdenudata is a small cactus with grayish-green spherical stems with 8 to 12 ribs sparsely lined with white wooly areoles that bear a few very short spines. The stems grow up to 3.2 inches (8 cm) tall and up to 4.8 inches (12 cm) in diameter, usually solitary or slowly producing offsets at the base. Each areole bears one central and 3 to 7 radial spines. The fragrant night-blooming flowers are white, funnel-shaped, up to 9 inches (22.5 cm) long, and appear in summer.
This cactus is usually treated as a synonym of Echinopsis ancistrophora.
USDA hardiness zones 9a to 11b: from 20 °F (−6.7 °C) to 50 °F (+10 °C).
How to Grow and Care
If you can grow cacti and succulents successfully, you can likely grow the Echinopsis species without too much trouble. Like many cacti, they prefer a drying period between waterings, even to the point where they slightly wilt. When you water, however, you should water deeply. The plant will noticeably plump up. The cactus mustn't be exposed to prolonged dampness and sitting water. Never let your cactus sit in a dish of water. Lastly, make sure to fertilize during the growing season for the best results.
Echinopsis can be easily rooted from offsets, which tend to cluster around the base of the mother plant. Cut offsets close to the stem, at the narrowest possible place. When rooting cacti from cuttings, let the fresh cutting dry out slightly on a paper towel and cut the cacti at the narrowest place possible. After a few days to a few weeks, depending on the size of the cut surface, the cut surface should have dried out and formed a callous or slightly rough opening. Once the callous has formed, place the cutting in a rooting mixture of fast-draining cacti soil.
