It is very important to plant as soon as possible after you receive them. If it is necessary to store them for a short time before planting them, open the plastic bags. If the roots appear dry, soak them for a few hours in warm water. Store in slightly moist peat moss in a cold, but not freezing location until you can plant. They can also be placed in pots of soil if planting will be delayed for more than 2 weeks. Use any peat-based potting soil and pots with drainage holes. Soak bare-root perennials in water for a few hours before planting.
Plant in full sun and slightly alkaline soil. Planted the crown (where the shoots meet the roots) an inch below the soil surface. Firm soil gently to eliminate air pockets and water in well. Mark the area clearly since it may be awhile before the plant shows itself. The most critical factor is good drainage. This plant will NOT tolerate wet soil, especially in winter. When planting, put a thick layer of gravel in the bottom of the hole and then mix more in with the filler soil.
