Astrophytum Myriostigma ‘Multicostatum’ 7 ribs Big size

Astrophytum Myriostigma ‘Multicostatum’ 🌿 — Scientific name: Astrophytum myriostigma f. multicostatum (Cactaceae). A many-ribbed horticultural form of the Bishop’s Cap cactus from the arid highlands of Mexico, it replaces the usual five ribs with numerous narrow ribs that create a refined, geometric column. Spineless and dusted with white trichome “flakes,” the matte green body reads like living sculpture, perfect for minimalist shelves and sunny windows.
FLOWER DETAILS
Mature plants produce silky, diurnal blooms in spring to summer: wide, lemon-yellow petals with a warm orange to red throat, opening in succession from the crown. Individual flowers last a few days and appear intermittently during the warm season.
CARE INSTRUCTIONS
☀️ Light: Full sun to very bright light; acclimate to direct sun to avoid scorch.
💧 Water: Soak thoroughly, then let the mix dry completely; water sparingly in cool seasons and keep almost dry in winter dormancy.

🪴 Soil: Fast-draining, mineral-rich cactus mix (pumice/perlite, coarse sand, small gravel with a modest organic fraction).
🏺 Potting: Unglazed terracotta with ample drainage; up-pot only when roots fill the container.
🌱 Growth rate: Slow to moderate; faster with strong light, warm days, and cool, dry nights.
