Description
Echinopsis huascha var. grandiflora is a basally branching cactus with globose to short-cylindrical. It somewhat resembles Echinopsis schickendantzii but has mostly bright red flowers. The stems grow up to 3 feet (90 cm) tall and 4 inches (10 cm) in diameter. They have reddish, much shorter spines than Echinopsis huascha. Diurnal flowers are funnel-shaped, up to 4 inches (10 cm) long, and appear near the end of the stems.

Hardiness
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 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 fertilizer 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.
