I was wondering if someone could tell me more about the perennial plant Sidalcea Elsie Heugh and whether it is able to tolerate/survive our winters in Toronto, Ontario, Canada.
I discovered this plant in one of our garden centers today and when I looked at the description, it stated that the plant is for Zone 4A.
I was curious if this plant would be able to survive the cold temperatures that we encounter here in Toronto.
If so, do I need to protect the plant with mulch or hay before the onset of frost? If so, when should I commence covering the plant with some winter protection.
Any information you can provide me is appreciated.
Prairie mallow ‘Elsie Heugh’ (Sidalcea ‘Elsie Heugh’), should be able to survive winters in Toronto without any special care; however mulching can lessen chances of winter kill.
Sidalcea stems are upright, and nice for cutting. Attractive to both butterflies and hummingbirds. Prune back hard after blooming, and plants may flower a second time in the fall. Should be divided every 2 to 3 years in early spring. Not terribly tolerant of hot humid summers.
Sidalceas grow best in full sun or light shade and rich, moist, well-drained soil with an acidic pH. Water regularly; plants do not like to dry out.
