Stalked Bulrush is a perennial grass native to Canada and the lower 48 states. It grows to 6.6 ft and blooms Jul in part shade – shade, with brown fruit.

Rain garden / bioswale — Rated OBL on the wetland list — tolerates wet feet, so it suits the soggy zone of a rain garden or bioswale that catches and filters runoff.Open guide →

Species characteristics from USDA PLANTS (public domain) + TRY (CC BY) — general guidance, not a
guarantee for your exact site. Deer "browsing" is documented palatability, not a deer-proof claim.
Native butterfly & moth caterpillars are the base of the terrestrial food web — most
songbirds rear their young almost entirely on them. As a host for native Lepidoptera this is
a moderate genus.
Recorded feeding on Scirpus in North America, including:
Keystone count (genus-level) from Warren II 2026 (CC0) · Tallamy host-use records. Named species (a documented Nearctic sample, not exhaustive) from NHM HOSTS (CC0).

We take the plant’s U.S. county range and look up each county’s long-term climate, then summarise: native rainfall = the median annual rainfall across its counties; heat tolerance = the warm end (90th percentile) of average temperature across its range (mirroring how our cold-hardiness floor uses an extreme). Counties + medians blunt the roadside/observer bias that makes point-level climate unreliable. Needs at least five placeable counties.
Honest limits: A realized, sampling-biased niche (where it has been recorded, not its physiological optimum), and county climate is coarse — large Western counties span deserts and mountains. Derived guide, never a measured fact.
