Manitoba Notes
In Zone 3–4 Prairie gardens, choose a sunny, well-drained spot (raised beds or gravelly soil help). Plant in fall before the ground freezes and mulch lightly after frost. Spring moisture is welcome, but avoid standing water. Flower stalks can reach ~48" in ideal conditions; stake if windy.
