Washington hawthorn is a small rounded deciduous tree from the eastern United States. The three- to five-lobed, maple-like leaves change from purple when new to glossy dark green in summer to orange or red in fall. Flat clusters of scented white flowers appear in late spring or early summer, followed in fall by bright red berries that hold through much of winter, attracting songbirds. The spreading, horizontal limbs brandish long thorns. The snow-frosted thorns and berries are a highlight of the winter landscape.
This graceful, multi-seasonal tree prospers in full sun and most neutral to slightly acidic soils. Unlike most hawthorns, it tolerates hot humid summers. Use it as a specimen or massed in the lawn, along streets, or for hedging and screening.

1. Soak in hot tap water for 24 hours
2. Cold/moist stratify for 90 days in moist vermiculite or sterile soil.
3. Sow seed 6 mm (1/4") deep, tamp the soil, lightly mulch the seed bed.
Plant the seeds in a container in a mixed medium of horticultural sand and peat or another organic material at a ratio of 1:1. Never plant firethorn seeds in regular soil.
When planting seeds in the fall, cover the peat/sand mixture with a layer of coarse grit, available at garden supply stores, and leave them outdoors for the winter. Seeds planted in the spring don't require coarse grit, though it helps.
