Brick Red Flowered Cactus
Overview
Echinopsis lateritia is a globose to cylindrical cactus species belonging to the family Cactaceae, highly regarded by collectors for its solitary growth habit and brilliant brick-red flowers. It is well-adapted to survive arid environments 1.
Taxonomy and Naming
Described in the 20th century, the specific epithet "lateritia" is derived from the Latin word for brick-colored, indicating the striking, fiery orange-red hue of its large funnel-shaped flowers 2.
Distribution and Habitat
This species is native to the high-altitude dry valleys and rocky slopes of Bolivia in South America 1. It thrives in gravelly, low-nutrient soils at elevations between 1500 and 3000 meters above sea level, exposed to intense solar radiation.
Appearance
The stem is light green to glaucous-green, growing up to 15-20 cm high, with 10 to 15 distinct ribs. Areoles bear strong, rigid, greyish-brown spines. The magnificent flowers emerge from the upper part of the stem during early summer, presenting a vibrant brick-red or coppery-orange color.
Cultivation
In cultivation, this cactus requires direct sunlight and moderate watering during the warm growing season. To promote healthy growth and subsequent flowering, it must be kept dry and cool (around 5-10 °C) during its winter dormancy 2.
Common Cultivation Mistakes
The most prevalent issue is overwatering combined with poorly draining soil, which quickly leads to root rot. Insufficient light causes the plant to stretch (etiolate), weakening its spine structure and preventing flower production.

Frequently Asked Questions
How often should Echinopsis lateritia be watered?
Water only when the soil is completely dry during summer (about every 10-12 days). In winter, withhold water completely.
Is this cactus toxic to pets?
It is non-toxic, but its sharp, rigid spines pose a physical hazard to curious pets.
How can I encourage it to bloom?
Provide ample direct sunlight in summer and ensure a cool (5-10 °C), dry winter dormancy period to trigger bud development.
When should I repot this cactus?
Repot every 2-3 years in spring, only when the root system has completely outgrown its current pot.
What kind of soil does Echinopsis lateritia prefer?
It prefers a highly mineral, fast-draining cactus mix containing pumice, coarse sand, and minimal organic matter.
Can it stay on the balcony during winter?
It can tolerate short drops down to -5 °C if kept completely dry, but it is best protected from severe frost.
What is its growth rate?
It has a slow to moderate growth rate, gradually developing into a small cylinder over many years.
Can it grow in partial shade?
It can survive, but it may stretch (etiolate), lose its dense spine color, and fail to produce flowers.
What are the most common diseases?
Root and stem rot due to overwatering, along with mealybug infestations in poorly ventilated areas, are the most common.
How long do the flowers last?
The stunning brick-red flowers open in early summer, with individual blooms lasting for a few days.
