    • Plant in full sun
    • Plant in organic, but well-drained soil; drought tolerant
    • Remove old foliage after frost
    • Divide in early spring
    • Height: 3-4 feet
    • Width: 2 feet, slowly spreading

    Hardy in USDA zones 4-9:

    • Zone 4: Plant in spring to prevent winter heaving; plant in full sun; apply extra mulch after first hard frost; avoid contact with salt; may be marginally hardy in this zone unless protected or covered by snow.
