Planting & Care

Plant rhizomes 2 inches deep and 12–18 inches apart in well-draining soil with the pointed end facing upward, adding mulch for winter insulation. For container growing, use a 12-inch pot with drainage holes, planting 1 inch deep in fertile, well-draining potting mix; the plant blooms best when slightly pot-bound. Water regularly until established, maintaining average to moist soil conditions, and provide supplemental water during extended drought or heat. Apply a thick mulch layer to retain moisture and protect roots from temperature fluctuations. Fertilize in spring and again two months later, then prune spent stems in late autumn and tidy the plant in early spring as it begins active growth.
