How to Overwinter a Charmed Wine Plant
Charmed Wine (oxalis), one of several shamrock varieties, can fill a shady or partly sunny growing area with plentiful foliage and delicate pink blossoms. Hardy in USDA zones 8 through 11, growing Charmed Wine in colder regions requires special winter care to prevent the plant’s demise. Overwinter a Charmed Wine plant to keep it healthy and vibrant from year to year and the plant will respond with new growth each spring. Does this Spark an idea?
