Echinopsis huascha is a slow-growing cactus with upright or creeping stems with 12 to 18 ribs and clusters of yellowish to brownish spines. It branches at the base to form up to 3 feet (90 cm) tall clumps. Stems are light green, cylindrical, and up to 3.2 inches (8 cm) in diameter. Each areole bears 1 to 3 central and 9 to 11 radial spines. The radial spines are up to 0.6 inches (1.5 cm) long, while the longer central spines are up to 2.4 inches (6 cm) long. Flowers are diurnal, scentless, funnel-shaped, and vary in color from red to orange and yellow. They are up to 4 inches (10 cm) long, up to 3 inches (7.5 cm) in diameter, and appear near the end of the stems from spring to early summer.
USDA hardiness zone 9b to 11b: from 25 °F (−3.9 °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, ensure fertilizer during the growing season for the best results.
Echinopsis can be easily rooted from offsets, which tend to cluster around the mother plant's base. 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, 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.
