Monvillea Spegazzinii (Moonlight Cactus)

Monvillea spegazzinii
Common Name: Moonlight Cactus

Monvillea spegazzinii, often called the Moonlight Cactus, is a fast-growing, sprawling to climbing cactus native to South America. Known for its serpentine stems, vivid green color, and occasional dramatic night-blooming flowers, this species brings a wild, jungle-like vibe to any cactus collection.

The stems are slender and ribbed, with short, bristly spines and a semi-epiphytic growth habit that allows it to sprawl, climb, or trail depending on its environment. It’s an excellent candidate for hanging baskets, trellises, or the edge of a planter where it can cascade freely.

☀ Light Requirements
Prefers bright indirect light to full sun. Can tolerate some shade, especially in hot climates. Too much direct sun without acclimation may cause stress.

💧 Watering Needs
Water when soil is completely dry, then soak thoroughly. During active growing seasons, it appreciates a bit more moisture than desert cacti, but always ensure excellent drainage.

🌡 Temperature Tolerance
Best kept above 35°F. Protect from frost. For winter orders or cold climates, we recommend adding a [Heat Pack].

✨ Special Features
• Vining Growth Habit – Unique among cacti; great for hanging or climbing displays
• Night-Blooming Potential – Can produce large, showy, fragrant blooms at night
• Fast Grower – Fills in space quickly with wild, tropical appeal
