The Astrophytum ornatum f. nudum is a unique and elegant form of the well-known Monk’s Hood Cactus. Like the standard species, it is a columnar cactus with strong vertical ribs, but its defining feature is the absence of the characteristic white, woolly scales that usually cover Astrophytum ornatum. The word nudum translates to “naked,” a fitting description of its smooth green to dark-green stem, which gives the plant a refined, sculptural appearance.
 
Over time, mature plants can reach impressive heights, developing into commanding columnar specimens with striking rib structure and a clean, polished look. This rare form is often sought after by collectors for its bold simplicity, which contrasts beautifully with the more speckled and patterned forms of the species. Some synonyms and closely related names are occasionally used for this form, reflecting its popularity and subtle variation within cultivation.
 
Our plants are offered at a mature size, already showcasing the distinctive smooth body that makes this form so desirable. Easy to grow with proper care, it thrives in bright light, very well-draining soil, and a thoughtful watering routine. With its elegant silhouette and rarity in cultivation, Astrophytum ornatum f. nudum makes a striking centerpiece for any serious cactus collection.
 
Caution: Toxic if eaten.
