Echinopsis subdenudata f. cristata 'Frosty Top' (Syn. Echinopsis ancistrophora) – A Snow-Capped Crested Cactus

Echinopsis subdenudata f. cristata 'Frosty Top' is a unique crested cactus with dense, white spination that gives it the striking appearance of a snow-covered mountain ridge. Originating from a mutation in the standard Echinopsis subdenudata, this rare form has a fascinating, undulating structure combined with a frosty, woolly texture.

Distinctive Features

• Frost-Like Spination: Unlike typical crested forms, this variety has an abundance of fine, white spines that create a snow-dusted effect.
• Crested Growth: Develops into a sculptural, fan-like structure with contorted ridges, ensuring no two specimens are identical.
• Flowers: Produces large, white, night-blooming flowers with a delicate fragrance, enhancing its ethereal beauty.

Care Tips

• Light: Prefers bright, indirect sunlight or partial shade; excessive direct sun can scorch its spines.
• Water: Water sparingly, allowing the soil to dry out completely between waterings; reduce significantly in winter.
• Humidity: Tolerates low humidity; thrives in dry conditions.
• Media: Requires a well-draining cactus mix with added sand or perlite to prevent root rot.
• Temperature: Best suited for warm temperatures between 18-30°C; avoid exposure to frost.
• Fertiliser: Feed with a diluted cactus fertiliser every 4-6 weeks during spring and summer.
• Repotting: Infrequent repotting is needed as it prefers being slightly root-bound.

Additional Notes

• Handle with care to prevent damage to the delicate, woolly spination.
• Propagation is mainly achieved through grafting or cuttings due to its crested nature.
• Non-toxic to pets, making it a safe option for homes with animals.

With its extraordinary snow-capped appearance and elegant crested growth, *Echinopsis subdenudata f. cristata 'Frosty Top'* is a true botanical masterpiece. Its combination of dense white spination and sculptural form ensures it stands out in any succulent collection.
