Itoh Peonies
30-36" tall. Also known as Intersectional Hybrid Peonies, Itoh Peonies are a cross between herbaceous garden peonies and tree peonies and feature the best of both. Giant blossoms (like the ones on tree peonies) open just after the garden peonies have faded.
The growth habit is similar to garden peonies with attractive mounded foliage that dies back in the winter. Don’t cut it back to the ground in fall. Leave at least 6" of hardwood stems above the ground—next year’s buds need room to develop on the lower stems. Full planting and pruning instructions will be included with your order.
Herbaceous Perennial Plants
When you receive your order, open the bags and check the stock immediately. Roots and crowns should be firm and pliable. Surface mold is harmless and will not affect the plant’s future performance. Store plants in their packaging in a cool (35–40°) location until you are ready to plant. If it’s going to be awhile, you can pot up your perennials.
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.
