Distinctive Features

• Caudex: Large, underground caudex that stores water and nutrients. The caudex is typically a grey-brown colour and has a rough, textured surface.
• Stems: Slender, cylindrical stems that emerge from the caudex and grow upright. The stems are typically a grey-green colour and have a smooth texture.
• Leaves: Small, ephemeral leaves that appear briefly during the growing season. The leaves are typically a bright green colour and have a smooth texture.

Care Tips

• Light: Bright, indirect light is best. While it enjoys some direct sunlight, intense afternoon sun can scorch the stems.
• Water: Allow the soil to dry out completely between waterings. Overwatering can lead to root rot, so it's important to be cautious.
• Soil: Use a well-draining succulent or cactus potting mix. You can also add perlite or pumice to improve drainage.
