Queen of the Prairie
Filipendula rubra
Queen of the Prairie blooms from June through July.
Months here are Northern Hemisphere months; in the Southern Hemisphere, shift them by six months.
Growing Queen of the Prairie
Plant it in full sun. It prefers high water. It is hardy in USDA zones 3–9. Expect it to reach about 5 ft tall and 2.5 ft wide at maturity, in roughly 3 years (not yet checked).
No toxicity note is on file for Queen of the Prairie. That is not a clearance: check its safety for people and pets before planting.
What this means
Written with AI assistance and not yet checked plant by plant against recorded sources, so treat every fact above as a starting point. Its scientific name was checked against botanical registries, an audit keeps its values consistent with the rest of the library, and a July 2026 review re-read the main facts of every plant then in the library against horticultural authorities without recording a source for each, which is why none of that counts as checked here. The source-by-source check is working through the whole library in the open, and a checked plant says so in this row.
When to plant Queen of the Prairie
Plant Queen of the Prairie in early spring as soon as the soil is workable, or in early fall at least six weeks before your first frost, so roots establish in cool weather. In zone 6, the middle of its hardy zones 3 to 9, spring means March to May and fall means August or September. Once settled, it blooms from June to July.
Month-by-month timing for your zone is on the planting calendar; if you garden near zone 6, the middle of this plant's hardy range, start with zone 6 in March. Derived from the plant's category, zones and bloom months plus typical zone frost dates, not checked separately.

How far apart to plant Queen of the Prairie
Derived from the mature spread above by a fixed rule, not checked separately: spacing is the spread, center to center.
Space Queen of the Prairie about 2.5 ft apart, center to center, so each plant has room to reach its full width.
Add Queen of the Prairie to a garden plan and the planner draws it at its full width, so you see the spacing before you buy.
Good to know about Queen of the Prairie
Curated from university extensions, botanic gardens and other primary sources, with the source named on every note. A note reports what its source says; where that differs from a fact above, the fact above is this entry's stored value, and its mark says whether it has been checked.
Worth knowing
Consistent moisture is the master lever: wet soil lets it take more sun without scorching, wards off powdery mildew, and (in rich ground) speeds its rhizome spread. per Illinois Extension and Morton
Full sun or part shade?
Sources disagree, and moisture is the tie-breaker. Full sun where the soil stays reliably wet and summers are cool, part shade in hot-summer regions to stop scorching. per Illinois Extension and Morton
Spreads by underground rhizomes
It creeps by underground rhizomes and self-seeds into long-lived colonies, fastest in rich, moist ground. Give it room, or spade the perimeter each spring to contain it. per Morton and Missouri
Pollen for bees, not nectar
The fuzzy plumes are stamen-dense and give pollen, not nectar, so the visitors are pollen foragers: bees (including sweat bees), beetles and flies, plus some butterflies. per Morton and Lady Bird Johnson
Deer and rabbit resistant
Both deer and rabbits mostly pass it by; it is rated deer-resistant and seldom damaged by rabbits. Very hungry wildlife may still sample it. per Iowa State and Morton
Buy nursery stock, never wild
In the wild it is a fen specialist and is state-listed as endangered or threatened in several states, so buy nursery-propagated plants and never dig it from the wild. per Illinois Extension and Michigan Natural Features Inventory
What pairs well with Queen of the Prairie
Good companions share its growing conditions and add something it lacks: an earlier or later bloom, a lower carpet in front, or structure through winter.
Flowering Crabapple
Shares full sun and moderate to high water; blooms in mid spring, before this one opens; both offer pollinator forage, in different months; taller at 20 ft, for the layer behind it.
Winterberry
Shares full sun and high water; blooms in mid fall, extending the bed's season; both offer pollinator forage, in different months; both are North American natives.
Wisteria
Shares full sun and moderate to high water; blooms in mid spring, before this one opens; both offer pollinator forage, in different months; climbs to 26 ft behind it, height without the footprint.
Joe Pye Weed
Shares full sun and high water; overlaps, then carries the display into early fall; its seed heads stand through winter, for structure and the birds; both offer pollinator forage; this one spreads, so it will crowd its neighbor in time.
Eastern Redbud
Takes full sun to part sun and moderate to high water; blooms in mid spring, before this one opens; both offer pollinator forage, in different months; taller at 23 ft, for the layer behind it.
Bee Balm
Shares full sun and moderate to high water; overlaps, then carries the display into late summer; both offer pollinator forage; lower at 3 ft, for the front of the border.
Perennial Sunflower
Shares full sun and moderate to high water; blooms in late summer as this one finishes; both offer pollinator forage, in different months; its seed heads stand through winter, for structure and the birds; this one spreads, so it will crowd its neighbor in time.
Tulip Tree
Shares full sun and moderate to high water; opens in late spring and overlaps into this one's season; both offer pollinator forage; both are North American natives.
