Harvest calendar

Best planted in early spring after your last frost, or in fall before the ground freezes, depending on your climate.

Prairie rose is a small, tough, deep-rooted species of the North American plains, dying back to the crown each winter. Its hips are small and thin-fleshed compared with rugosa or villosa — closer in character to arctic rose's — valued historically more for jelly, tea, and wildlife forage than for thick preserving flesh. ⚠ Deseed the hips before eating: the ring of stiff hairs around the seeds is a gut and skin irritant, and is what old-fashioned itching powder was made from. Strain it out of any purée or syrup.

Native range

Central North America between the Rocky Mountains and the Appalachians — from Alberta, Saskatchewan, and Manitoba south through the Great Plains to Texas and New Mexico, and east through the Dakotas, Nebraska, Kansas, and Indiana. Naturalized locally outside this range in Massachusetts, New York, and North Dakota.

Status

Wild

Years to fruit

2–4 yrs

Growth speed

Medium; dies back substantially each year and regrows from the root crown rather than building height steadily.

Spacing

90 cm (35 in) apart — about 1.2 per m² (1.1 per 10 sq ft)

Leaf shape

Leaves are alternate and pinnately compound with 7–11 leaflets (most commonly 9 or 11 — a useful identification feature distinguishing it from the fewer-leafleted Rosa blanda). Leaflets are broadly oblong to oblong-obovate with coarsely serrated margins. Stems are thorny and flexible.

Root system

Non-suckering in the rhizomatous sense — it does not spread by underground runners — but has an unusually deep, stout taproot-and-crown system (recorded to 8–12 feet deep) from which it resprouts vigorously after top damage from fire, frost, or drought.

Fruit description

Hips are small, round to slightly elongated, bright red, about 12–15mm in diameter, maturing in late August through September and persisting through winter. Flesh is thin around the numerous seeds, but the hips are documented as rich in vitamin C and were used by settlers for rose hip jelly and by Plains peoples as a food source; they are also heavily eaten by birds and mammals through fall and winter.

Propagation

Rose seed is slow and erratic to germinate — a hard seed coat and immature embryo mean stored seed cold-stratified 6 weeks at 5°C can still take 18–24 months to come up; sowing green (unripe) seed immediately sometimes germinates by the following late winter instead. Also propagated by half-ripe cuttings in July, hardwood cuttings 20–25cm long in early autumn, layering, and by dividing root-crown suckers during dormancy.

Pollination

Flowers are bee-pollinated. It is the source of the North Dakota state flower and was historically the basis for Iowa's state flower designation (as the synonym Rosa pratincola), reflecting its regional importance to prairie pollinators.
