The Pencil Plant or Euphorbia Tirucalli is a succulent native to South and East Africa. The plant’s namesake branches are pencil-like and grow upward in a candelabra pattern. Young branches are cylindrical, smooth, and green, but with age can turn gray and rough like tree bark. Its leaves are small and slender and fall off quickly. This succulent yields a highly toxic milky sap if broken or torn. The Pencil Plant is otherwise very agreeable, surviving in nearly any condition that is both dry and above freezing. In favorable conditions, it is able to grow between two and 20 inches in a single season.
Thrives in bright indirect light to direct sun. Not suited for low light conditions.
Water every one to two weeks allowing soil to dry out between waterings. Increase frequency with increased light.
Don’t sweat it. Average home humidity is fine; can tolerate dry air.
Prefers temperatures of 65°F-70°F. Average home temperature is generally suitable.
Given the right indoor conditions, a Pencil Plant can grow to 6’.
As with all succulents, overwatering will lead to rot.
SYMPTOM: Dropping individual branches
The sap of the Pencil Plant is quite toxic. Wear gloves when handling to prevent irritation from the sap; wash hands well after handling. If sap is exposed to eyes or swallowed, seek immediate medical attention.
Best practice is always to keep houseplants out of reach of small children and pets.
