Spider Cactus
Gymnocalycium horstii
Compact, round, and beautifully detailed, Gymnocalycium horstii is a small cactus with serious charm. Its ribbed, globe shaped body is lined with fine, spider like spines that give it its common name without looking overly fierce.
Neat and symmetrical, it’s perfect for sunny windowsills, desks, or adding contrast to a mixed cactus collection. Small in size, but full of character.
Subtle. Structured. Effortlessly cool.
✨ Why we love it:
🌵 Ribbed, rounded globe shape

🌵 Compact and space friendly
🌵 Can produce delicate pale pink to white flowers
💡 Light: Thrives in bright light with some gentle direct sun. Avoid harsh midday rays.
💧 Water: Allow the soil to dry out completely between waterings. Reduce watering significantly in winter.

🐾 Pet/Child Safe? Not toxic, but the spines can be sharp. Best kept out of reach of curious hands and paws.
