Piet Oudolf names just a few of his favorites and explains their appeal

Garden designer Piet Oudolf has gained international renown for his imaginative plantings. One of his design strategies is to include many plants that bloom late and look good as they go to seed. The result is a garden that looks just as appealing in fall and winter as it does in spring and summer. The perennials recommended here are characterized by appealing seed heads and distinctive structural outlines.

Links in the lists below will take you to full descriptions of the species or genus in Fine Gardening 's  Plant Guide.
