Rebutia-flowered Matucana
Genel bakış
Matucana rebutiiflora is a rare and highly prized cactus species belonging to the Cactaceae family 1. Native to the high-altitude Andean regions of Peru, this species is well-known for its compact growth habit and vibrant, Rebutia-like flowers.
Sınıflandırma ve adlandırma
When first described in botanical literature, it received the specific epithet rebutiiflora due to its characteristic flowers resembling those of the genus Rebutia 2. The genus Matucana is named after the Peruvian town of Matucana.
Doğal yayılış ve habitat
This cactus naturally occurs on the western slopes of the Peruvian Andes, typically on steep, rocky cliffs at elevations exceeding 2000 meters above sea level 1. This extreme habitat has adapted the plant to highly draining mineral soils and drastic day-night temperature swings.
Görünüm
It grows as a slow-growing, globose to slightly cylindrical succulent subshrub. The green stem is divided into distinct ribs, adorned with aeroles bearing thin, flexible spines. During spring and summer, it produces striking yellow, orange, or reddish funnel-shaped flowers near the apex.
Kültürde bakım
In cultivation, it thrives under filtered sunlight rather than scorching midday sun. It requires an extremely porous gritty mix. Watering should be deep but infrequent, and the plant must be kept completely dry during its winter dormancy 2.
Sık görülen bakım hataları
The most common mistake is overwatering, especially in poorly draining pots, or keeping the plant in warm, humid rooms during winter, which prevents dormant rest and causes root rot.

Non-toxic, but the small spines can cause physical irritation; keep out of reach of pets and children.
Difficulty
Moderate
Moderately easy for indoor growers, provided the watering schedule and soil drainage are strictly managed.
Native Habitat
Peru

Frequently Asked Questions
How often should I water Matucana rebutiiflora?
Water when the soil is completely dry in summer (about every 10 days). Suspend watering entirely during winter.
What type of soil does it prefer?
It prefers a highly mineral, well-draining cactus mix rich in pumice, volcanic rock, and river sand.
Why is my Matucana cactus not blooming?
To bloom, it needs a cool (5-10°C) and completely dry winter dormancy, followed by plenty of bright sunlight in spring.
Is it toxic to pets?
No, it is non-toxic, but its fine spines can cause mechanical injury to pets' mouths or paws.
What are its sunlight requirements?
It loves bright, filtered sunlight. Protection from intense, direct midday sun prevents sunburn.
What is its growth rate?
It is a very slow-growing, compact cactus, meaning it rarely needs repotting or large containers.
Is it cold hardy?
It can tolerate brief drops down to 2°C (35°F) only if the soil is completely dry, but it must be protected from frost.
When should I repot it?
Repot in early spring every 2-3 years, only when the root system has completely filled the current pot.
How do I recognize root rot?
Softening at the base, discoloration (yellowing or browning), and a complete stop in growth are signs of root rot.
How should I fertilize it?
Apply a half-strength, high-potassium cactus fertilizer once a month during the spring and summer active growth phase.
