Hedera colchia “Sulphur Heart”


The large leaved variegated ivy ‘Sulphur Heart’ has bright gold and lime green variegations that are invaluable for bringing splashes of light to a dark shady wall. In light shade, mingle it with winter jasmine and Cotoneaster horizontalis for a plant association with even greater variety and all year round interest. ‘Sulphur Heart’ clings to brick walls and similar textured surfaces so long as its aerial roots can get a grip. Splash walls with water to help new plants start clinging, but don’t grow where the mortar is unsound or the roots may cause damage. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).
