From West Cook Wild Ones:
Many gardeners wonder what native plants will thrive under tree canopy. Roy Diblik with decades of landscape design experience can guide you in choosing native woodland plants that grow happily in shade gardens. Roy uses texture and color to create welcoming, shady spaces. He will teach us how to plant sedges (aka Carex species) as a ground layer of living mulch. Roy will explain how to build on this bottom layer by adding in spring ephemerals, ferns and other woodland species for bursts of color and interest during the garden season.
Roy Diblik is a recognized perennial plant expert, grower, designer, speaker and author. Combining his 35 years of knowledge growing traditional and Midwest native perennials, he specializes in highly aesthetic, sustainable plant communities for all seasons, while reducing maintenance through design. He believes that gardens should be thoughtful, ecologically directed, emotionally outreaching and yet very personal.
