• 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.

Care Tips

• 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.
