Overview
Echinopsis schieliana (synonym Lobivia schieliana) is a small-growing, clumping perennial succulent subshrub in the Cactaceae family 1. Native to the high-altitude Andean regions of Peru and Bolivia, this species is highly valued in amateur collections and rock gardens.
Taxonomy and Naming
Originally described in the mid-20th century, the species was named in honor of the German cactus enthusiast Schiel 2. While long categorized under the genus Lobivia, contemporary molecular taxonomy groups it within the broader genus Echinopsis 1.
Distribution and Habitat
This cactus thrives in the montane tropical biomes of the Andes, occurring at elevations between 3,000 and 4,000 meters 2. It grows primarily on rocky, well-draining slopes exposed to intense solar radiation and low organic matter.
Appearance
The stems are globose to short-cylindrical, light green, clustering freely from the base to form dense cushions. Areoles bear numerous pectinate, thin, needle-like spines. In spring and summer, it produces vibrant funnel-shaped flowers in shades of red, orange, or yellow 1.
Cultivation and Care
It requires a highly porous, mineral-rich substrate. While it enjoys bright conditions, filtered sunlight is preferred during intense summer heat. Kept completely dry in winter, it can tolerate brief frosts down to -2°C 2.
Common Cultivation Errors
Overwatering and poor soil drainage are the most frequent causes of root rot. Additionally, keeping the plant warm and wet during winter prevents the essential dormancy period needed for spring flowering.

Watering
7-28 Days
Allow the soil to dry out completely between waterings. Keep absolutely dry throughout the winter cold.
Soil
Well-draining, pumice and sand grit-heavy cactus soil mix
Thrives in a highly porous mineral mix with plenty of pumice, perlite, and coarse sand.
Safety
Pet Friendly
Non-toxic to pets, but the sharp pectinate spines can cause mechanical injury. Keep out of reach.
Difficulty
Easy
Very easy to grow if watering is kept minimal and winter dormancy is properly maintained.
Native Habitat
Southern America (Bolivia, Peru)
Hailing from the high-altitude montane tropical zones of the Andes, this species is adapted to intense sunlight, dry air, and rocky, nutrient-poor soils that experience sharp temperature drops at night.
Frequently Asked Questions
Is Echinopsis schieliana easy to grow indoors?
Yes, it is very easy to grow indoors provided it receives ample sunlight and proper watering.
How often should I water this cactus?
Water roughly once a week in summer after the soil dries out completely, and keep it nearly dry in winter.
What type of soil should I use?
Choose a highly porous cactus mix rich in pumice, sand, and volcanic grit to ensure fast drainage.
When does Echinopsis schieliana bloom?
It blooms in late spring and summer, producing funnel-shaped red, orange, or yellow flowers.
How can I encourage it to bloom?
A cool, dry winter dormancy period at 5-10°C without watering is essential for flower bud initiation.
Is it toxic to pets?
It is not chemically toxic, but its sharp spines can cause physical injury to curious pets.
Can I propagate it using offsets?
Yes, you can easily propagate it by removing basal offsets in spring, letting them callus, and potting them.
Can it stay on the balcony during winter?
If kept completely dry, it can survive short frosts down to -2°C, but a sheltered indoor spot is safer.
How fast does it grow?
It has a slow to moderate growth rate but forms attractive, dense cushion-like clumps over time.
Why is my cactus turning yellow and soft?
This is usually a sign of root rot caused by overwatering. Stop watering immediately and check the roots.
