Overview

Matucana pujupatii is a rare and highly sought-after cactus species belonging to the Cactaceae family, native to the inter-Andean valleys of Peru. Noted for its beautiful globose, blue-green stem and vibrant asymmetrical flowers, it is a prized specimen among succulent enthusiasts ¹.

Taxonomy and naming

The genus Matucana is named after the Peruvian town of Matucana, located near Lima. The specific epithet 'pujupatii' honors local botanical guides or collectors associated with its discovery. It belongs to a genus known for its distinct, bird-pollinated floral structures ².

Distribution and habitat

This species is endemic to Peru, particularly restricted to the Marañón River basin within the Amazonas and Cajamarca regions. It thrives at elevations of 1,000 to 1,500 meters above sea level, clinging to steep, rocky cliffs and dry shrubland areas with minimal organic soil ¹.

Appearance

The stem is solitary or slowly offsetting, glaucous grey-green to bluish-green, reaching up to 15 cm in height. It features 10 to 12 low, tuberculate ribs. The spines are strong, curved, initially dark brown to blackish, and fade to grey with age. Its striking diurnal flowers are funnelform, zygomorphic, and display a brilliant crimson or orange-red hue.

Cultivation and care

In cultivation, Matucana pujupatii requires an extremely gritty, free-draining mineral mix and excellent air circulation. Water thoroughly during the active summer growing season, allowing the substrate to dry completely between applications. During winter, it must be kept dry and cool (around 8-10 °C) to stimulate blooming ².

Common care mistakes

The most prevalent issue is overwatering combined with poorly draining soil, which inevitably leads to root rot. Insufficient light causes the plant to stretch (etiolate), losing its compact, globular form and reducing its ability to flower.

Filtered Sun

Thrives in bright, filtered sunlight; direct midday sun should be avoided in extreme heat.

10-30 Days

Water only when the soil is 100% dry; keep absolutely dry during winter dormancy.

Highly porous, pumice and coarse sand grit cactus mix

Use a grit-heavy mix composed mostly of pumice, lava rock, and coarse sand.

Pet Friendly

Non-toxic to pets, but the sharp, curved spines can cause mechanical injury if handled carelessly.

Moderate

Moderate. Demands strict watering discipline to prevent root rot, making it best for intermediate growers.

Western South America, Peru

Endemic to the steep rocky slopes and dry river valleys of the Amazonas and Cajamarca regions in Peru, thriving in highly mineral, well-draining soils.

Frequently Asked Questions

How often should I water Matucana pujupatii?

Water it only when the soil is completely dry (about every 10 days in summer). Keep it completely dry during winter.

Is this cactus toxic to pets?

It is non-toxic, but its sharp, stiff spines can physically injure curious pets.

How do I encourage it to bloom?

Provide a cool (8-10 °C) and completely dry winter dormancy period to stimulate flower bud initiation in spring.

What type of pot and soil should I use?

Use unglazed clay pots with drainage holes and a highly porous grit mix containing at least 60% pumice or sand.

Does it need direct sunlight?

Bright filtered sunlight or morning sun is ideal; protect it from scorching, intense midday summer sun.

Is Matucana pujupatii a fast grower?

No, it is a relatively slow-growing cactus that maintains its compact, globose shape for many years.

Can it survive on a balcony during winter?

It can tolerate temperatures down to 8 °C if kept completely dry, but must be protected from freezing frost.

Why is my cactus stretching out of shape?

A stretching stem (etiolation) is caused by insufficient light, as the plant tries to reach towards a light source.

How is it propagated?

It is mainly propagated by seeds, or occasionally by carefully separating offsets from the base of mature plants.

What are the most common pests?

Mealybugs and root mealybugs are the most common pests. Overwatering can lead to fungal rot.
