Additional Information

Herbaceous Perennial Plants

When you receive your order, open the bags and check the stock. Roots and crowns should be firm and pliable. Generally, a little surface mold is harmless and will not affect the plant’s future performance. If they are slightly dry, add a little water or, if they are going to be planted or potted up soon, wet the roots. If you do not plant or pot them up immediately, store them in a cool (35–40°) location for a short time.

Do not plant bare-root perennial plant crowns directly outdoors before danger of frost has passed. Wet and/or cold conditions for an extended period may cause rotting.

Pot up rootstock using well-drained potting mix in a deep 6" pot or a 1-gallon container. Avoid coiling the roots in under-sized containers.
Grow newly potted perennials for a few weeks in a protected location in indirect light at 50–60°.
Transplant outside once they show some top growth and the danger of frost has passed.
