Euphorbia ingens – Bold Architecture from Southern Africa
Euphorbia ingens, also called the Candelabra Tree, is a dramatic succulent that can grow into a towering tree in its native habitat — but indoors, it becomes a manageable, sculptural showpiece. With its vertical ribs, branching silhouette, and striking green stems, this species is ideal for plant lovers looking for something bold and low-maintenance. As it matures, it may even bloom with greenish-yellow cyathia and form decorative, reddish-purple fruits.
Main Features of Euphorbia ingens
- Growth Habit: Can reach up to 15 m in the wild but stays smaller in containers, often forming a branching, tree-like silhouette.
- Stem Structure: Ribbed, upright stems (4–5 ribs) with paired spines and a smooth, green to bluish surface that darkens with age.
- Flowers & Fruits: Mature outdoor plants may produce small greenish-yellow flowers (cyathia), followed by dark red to purple capsule-like fruits.
Natural Habitat of Euphorbia ingens
Native to dry inland regions of South Africa, Botswana, Zimbabwe, and Mozambique, this species thrives in bushveld and open woodland, especially on rocky slopes and well-drained soils. It typically occurs at elevations of 400 to 1200 m, in areas with hot temperatures and sparse rainfall. It is well-adapted to intense sun, drought, and poor soil — key traits that make it a robust indoor plant.
How to Care for Euphorbia ingens Indoors
→ Light
- Needs bright light with several hours of direct sun daily.
- Best near a south-facing window or in a sunroom. Weak light leads to elongation and poor growth.
→ Water
- Water only when soil is bone dry — every few weeks depending on light and temperature.
- Reduce watering if light levels drop or temperatures fall — not based on season.
- Always use a pot with drainage to avoid root or stem rot.
→ Soil
- Use a gritty cactus mix with added pumice, lava rock, or coarse sand.
- Soil should drain fast and dry fully between waterings.
→ Temperature & Humidity
- Ideal temperature range: 20–30°C. Protect from cold below 10°C.
- Thrives in dry indoor air. No humidity trays or misting needed.
→ Fertilizing
- Feed monthly during active growth using a diluted cactus fertilizer.
- Pause feeding if the plant slows down due to low light or cold — not necessarily in winter.
→ Repotting
- Repot every 2–3 years or when the plant becomes top-heavy or root-bound.
- Use a sturdy, heavy pot with wide base — Euphorbia ingens can become unstable with height.
→ Propagation
- Propagation by cuttings is possible but slow. Let cuttings callous for at least 5–7 days before planting.
- Always use gloves and goggles — sap is highly toxic and causes strong skin and eye irritation.
Potential Problems with Euphorbia ingens
→ Overwatering / Stem Rot
- Symptoms: soft or blackened stems, mushy roots.
- Cut away affected tissue with sterilized tools and reduce watering frequency.
→ Pests
- Can attract mealybugs, spider mites, or scale insects on weakened plants.
- Use insecticidal soap or neem oil; ensure good air flow.
→ Yellowing or Shriveling
- Yellowing may be caused by overwatering or lack of light. Adjust both accordingly.
- Shriveling usually indicates underwatering or very dry root zone.
Handling Tips & Safety for Euphorbia ingens
- Sap Warning: Euphorbia sap is toxic and causes severe irritation. Wear gloves and eye protection when pruning or repotting.
- Placement: Keep away from pets, children, and high-traffic areas where accidental contact may occur.
Etymology of Euphorbia ingens
Euphorbia honors the Greek physician Euphorbus, who used related plants medicinally. The species name ingens means “huge” or “vast” in Latin — a nod to the impressive size and presence of this succulent in the wild.
