Euphorbia tirucalli, commonly known as Pencil Cactus, Sticks on Fire, or Milkbush, is a succulent shrub or small tree native to Africa. It is characterized by its thin, cylindrical, green branches that resemble pencils. The plant produces a toxic, milky latex that can cause skin irritation and is dangerous if ingested. In ideal conditions, it can grow up to 70 meters tall.
Habitat
Pencil Cactus thrives in arid and semi-arid regions, often found in dry forests, savannas, and rocky areas. It prefers well-drained soils and is highly drought-tolerant, making it suitable for xeriscaping.
Planting and Care
- Light: Full sun to partial shade.
- Soil: Well-draining, sandy or rocky soil.
- Watering: Water sparingly, allowing the soil to dry out completely between waterings. It is highly drought-tolerant.
- Maintenance: Minimal maintenance required. Prune to control shape and size.
Additional Information
