BEYOND HYDRANGEAS: CREATIVE COMPANIONS FOR THE SHADE GARDEN – PART 2
Don’t be lulled into thinking that because you have tall trees shading your yard you cannot have flowers. Foliage plays a large role in a shade garden, too. There are plenty of choices when it comes to perennials that will come back year after year. Here are just a few ideas from Jamie Blackburn, the Curator of Woodland Gardens with the Atlanta (GA) Botanical Garden Horticulture Department.
Jamie was a featured speaker at a recent Central Savannah River Area Hydrangea Society Conference. In last month’s GardenSmart Newsletter, Jamie shared a list of small trees, conifers, and vines suitable for shady gardens. This month, he has a few recommendations for perennials that will make it in the shade garden. – Anne K Moore
