Senecio Rowleyanus - String of Pearls
Senecio Rowleyanus - String of Pearls - is a succulent so treat it similarly to any other drought-tolerant, water retaining plant.
Bright, indirect light.
As a succulent it stores water in its leaves and is very drought tolerant. Allow the soil to dry out before watering again.
Overwatering is the killer. Be a little mean with the watering can.
