Planting
How to Grow
- Tuck seeds into well-draining soil in early spring for best germination.
- Water sparingly until seedlings establish, then maintain moderate moisture.
- Mist cuttings if propagating via stem segments, keeping humidity high.
- Ensure cactus or succulent soil mix for mature plants to prevent root rot.
- Fertilize lightly during active growth with a cactus fertilizer every 4–6 weeks.
- Transplant into larger pots when roots outgrow current containers, typically after 1 year.
Pro Tip
Use well-draining soil and avoid overwatering to prevent root rot.

Common Questions
Horned Spurge questions
What zones can Horned Spurge grow in?
Horned Spurge is hardy in USDA Zones 5–8. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Horned Spurge deer resistant?
Yes — Horned Spurge is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.
When does Horned Spurge bloom?
Horned Spurge typically blooms in mid-summer through late summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Horned Spurge need full sun?
Horned Spurge does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Horned Spurge drought tolerant?
Yes — once established (usually after the first full season), Horned Spurge handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
