The Story
Plant Bio
Pyracantha koidzumii, Formosa firethorn, is a fast semi-evergreen shrub from Taiwan, eight to eighteen feet tall and eight to twelve across. Narrow oblanceolate leaves cover thorny arching stems, clusters of small white flowers open in spring, and dense bunches of orange-red berries follow and hold well into winter.
The thorns are serious — stiff, sharp and hidden among the foliage, which makes this superb as a security hedge and unpleasant anywhere people brush past. Wear thick gloves and eye protection to prune it. It is also prone to fireblight, so cut only in dry weather and disinfect between cuts, and it trains beautifully flat against a wall.

Common Questions
Pyracantha questions
What zones can Pyracantha grow in?
Pyracantha is hardy in USDA Zones 7–9. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Pyracantha deer resistant?
Yes — Pyracantha is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.
When does Pyracantha bloom?
Pyracantha typically blooms in late spring through early summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Pyracantha need full sun?
Pyracantha does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Pyracantha drought tolerant?
Yes — once established (usually after the first full season), Pyracantha handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
