Lobivia Matuzawae
Overview
Lobivia matuzawae is a rare, globose cactus species belonging to the family Cactaceae, highly regarded for its striking diurnal flowers and neat spination 1. It is a coveted specimen among succulent enthusiasts and collectors.
Taxonomy and Naming
Classified under the genus Lobivia, this species shares close taxonomic ties with the broader Echinopsis group, and its classification has historically fluctuated between these two genera 1. The generic name 'Lobivia' is an anagram of Bolivia, the country where many species in this genus originate 2.
Distribution and Habitat
This cactus is native to the high-altitude Andean regions of South America, particularly Bolivia 2. It thrives in rocky crevices, gravelly soils, and barren environments subject to intense solar radiation and cool nights.
Appearance
The stem is solitary or slowly offsetting, globose to short cylindrical, with a green to grayish-green epidermis. It features distinct ribs lined with prominent areoles bearing rigid, slightly curved spines. During spring and summer, it produces spectacular funnel-shaped, vibrant red or orange flowers near the crown 1.
Cultivation and Care
In cultivation, Lobivia matuzawae requires extremely porous, mineral-heavy soil containing pumice or coarse sand. Watering should be thorough but infrequent, allowing the substrate to dry completely between sessions. During the winter dormancy, watering must be completely suspended to prevent root rot 2.
Common Cultivation Mistakes
The most prevalent error is overwatering during winter, which inevitably causes fatal root and stem rot. Additionally, keeping the plant in low-light conditions leads to etiolation, causing the natural globose form to stretch and weaken.

Watering
8-25 Days
Always let the soil dry out 100% before watering. Suspend watering entirely during the cold winter months.
Soil
Highly gritty cactus mix with abundant pumice, coarse river sand, and a minimal organic peat fraction.
Use a mineral-rich, extremely fast-draining cactus mix high in pumice, grit, and coarse sand.
Safety
Pet Friendly
Non-toxic, but features sharp spines that can cause minor injuries; keep out of reach of children and pets.
Difficulty
Easy
Very easy to maintain, provided that winter dormancy guidelines and strict watering rules are followed.
Native Habitat
Bolivia
Native to the high-altitude Andean areas of Bolivia, where it grows in rocky crevices and gravelly slopes under intense sunlight and dry, cool conditions.
Frequently Asked Questions
How often should I water Lobivia matuzawae?
Water thoroughly during spring and summer only when the soil has dried out completely (about every 7-10 days). Suspend watering entirely in winter.
Is this cactus toxic to pets?
No, it is non-toxic. However, its sharp spines can still cause physical injury to curious pets.
Where is the best place to keep it indoors?
A sunny, well-ventilated windowsill facing east or west is ideal for this cactus.
When does Lobivia matuzawae bloom?
It produces large, funnel-shaped flowers at the crown during late spring and summer, provided it went through a dry winter dormancy.
What type of soil does it prefer?
It prefers nutrient-poor, highly porous cactus soil with a high ratio of pumice and coarse sand for instant drainage.
Is winter dormancy necessary?
Yes. A cool, dry winter rest is essential for promoting healthy compact growth and stimulating spring flowers.
How fast does it grow?
It is a slow to moderate grower, typically maintaining its neat, compact globose shape for many years.
When should I repot it?
Repot every 2-3 years in early spring as needed, using a container only slightly larger than the current one.
Why is my cactus getting soft?
Softness is usually a sign of root rot caused by overwatering. Stop watering immediately and check the root health.
Can it be kept outdoors?
It thrives outdoors during summer. However, it must be brought indoors to protect it from frost and heavy rains during winter.
