Prunus persica 'Frost' Frost is a lucky chance seedling discovered at the WSU Mount Vernon testing station, where it performed well in 10-year trials for disease resistance, especially to peach leaf curl. It has proved to be a remarkably durable tree, sailing through disease attacks and continuing to set fruit and ripen crops even in less-than perfect conditions and locations. A tasty, yellow-fleshed peach, it is semi-freestone making it good for fresh eating and kitchen-made treats. Frost also excels as an ornamental tree due to its full, almost double-blossomed, rosy flowers! Ripens mid-season. Cold Hardy to USDA Zone: 5 Mature Height: 14' Sun: Full Sun Ripening Time: Mid-Season Pollination: Self Fertile Dwarf Rootstock: St. Julian A Semi-Dwarf Rootstock: Krymsk-1 Read our Peach Growing Guide
