I’m in Riverdale, Toronto, Zone 3. I bought several heuchera. Some have done well in part- sun/ part-shade. The one in the photo is in full shade in a corner near a well grown hydrangea vine and an established rose. It wasn’t doing well in a sunnier spot so I moved it last year to this shaded place but it doesn’t seem to be thriving. Do you have an suggestions, or recommendations on where to plant in in my mostly shady border? The soil is very sandy under much amended soil. I think it’s damp mostly because it’s so shady.
Thank you for contacting the Toronto Master Gardener.
Heuchera is a beautiful plant. Most heucheras do best in partial shade or dappled shade (not full shade) but many varieties develop their best leaf color in full sun. They prefer a slightly acidic pH and moist, well-drained soils that have been amended with organic matter such as compost. They are usually short-lived perennials unless divided every 3 to 4 years.
Best of luck.
