Botanical Name

PYRACANTHA koidzumii

Plant Common Name

Formosa Firethorn

General Description

The fiery fruits of this large gaunt evergreen shrub from Taiwan put on a spectacular show from fall into winter. Spiny red-brown branches set with whorls of oblong glossy green leaves bear clusters of small white flowers in spring. Globular to disk-shaped berries follow the flowers, ripening from green to orange-red in fall. The fruits persist well into winter, and are largely shunned by birds. This shrub is hardy only in areas with relatively mild winters.

Formosa firethorn does best in well-drained soil in full sun, and tolerates a wide variety of soils and exposures once established. Its rather ragged habit benefits from an occasional pruning. Its cultivars (including 'Santa Cruz' and ' Victory') and hybrids are preferable for landscape use, exhibiting better form and abundant colorful berries.

Formosa firethorn has escaped gardens in Australia, Hawaii, the southern United States, and other areas, and is sometimes considered a weed.
