Echinocereus Matthesianus

The Echinocereus Matthesianus is a small cactus native to Mexico, remarkable for its short columnar shape and its reddish to dark brown spines that give it a robust yet elegant appearance. Relatively little known, it attracts collectors with its compact habit and vivid flowering.

This cactus belongs to the Echinocereus genus, known for its bright flowers and varied forms. The Echinocereus Matthesianus forms an upright, slightly ribbed stem that can reach 10 to 15 cm in height and about 4 to 6 cm in diameter at maturity. It may remain solitary or slowly form small clumps.

Its skin color ranges from light green to olive green, sometimes with bluish reflections depending on exposure. The areoles are well spaced, bearing fine but firm spines, often dark red to reddish-brown. This warm coloration contrasts beautifully with its magenta-pink flowers with a paler center, which usually appear in spring or early summer.

The Echinocereus Matthesianus naturally grows in the semi-arid regions of northern Mexico. It inhabits rocky slopes among thorny shrubs and other xerophytic species. It is adapted to extreme conditions: intense sun, low rainfall, and very well-drained mineral substrates.

These living conditions have given it strong resistance to water stress and great tolerance to temperature variations, making it an ideal cactus for pot or greenhouse cultivation.

The Echinocereus Matthesianus loves light and needs it to maintain a compact shape:

🌞 Outdoors: full sun, ideally 6 to 8 hours of direct light per day.

🌤️ Indoors: near a south-facing window, or under LED grow lights.

⚠️ Warning: lack of light causes stem elongation (etiolation) and dull spine coloration.

Like all Echinocereus, the Echinocereus Matthesianus prefers light but regular watering during its growth period:

🌱 Spring / Summer: water every 15 to 25 days depending on heat. The substrate must dry completely between waterings.

🍂 Autumn / Winter: stop all watering. Winter rest is crucial to prevent disease and prepare flowering.

⚡ Tip: use non-calcareous water and avoid wetting the base to prevent rot.

The Echinocereus Matthesianus tolerates warm temperatures and slight winter coolness:

🌞 Ideal temperature: between 20°C and 32°C during its active phase.

❄️ Minimum tolerance: down to 2°C if the substrate is perfectly dry. Avoid any frost.

🏠 Wintering: indoors, dry, between 5°C and 10°C to stimulate spring flowering.

This cactus likes very mineral and well-drained soils:

🪨 Ideal substrate: 40% cactus soil, 30% pozzolana, 30% gravel or coarse sand.

💡 Good drainage prevents excess moisture, which is harmful to this type of cactus.

The Echinocereus Matthesianus offers spectacular flowering despite its small size:

🌼 Period: spring or early summer.

🎨 Color: magenta pink with a white or pale pink center.

🕑 Duration: 3 to 5 days per flower, with several flowers appearing successively.

💡 To encourage flowering, provide a strict dry winter rest and plenty of sun from March onward.
