Please Note: Our Ships Now perennials will currently ship dormant. The foliage and blooms begin to brown and die back. We provide a hard trim in the greenhouse to support this process. During dormancy, plants go inactive to conserve their energy for the next growing season. This happens naturally as seasons change!

You must select Size and Ship Week to see accurate sale price and availability.

Please note: Our Ships Now perennials are still waking up from dormancy. In the spring, as temperatures rise and daylight hours increase, perennials begin to emerge from dormancy, pushing new shoots from their roots. Most dormant plants start showing new growth in late March or early April, depending on the specific plant and local weather conditions.

Care: Clean away any dead foliage after frost. Fertilize with Proven Winners Continuous Release Plant Food in spring.
