Sparkle is the best strawberry for jam and freezing. Sparkle has been known for flavorful, high-quality, attractive fruit for over 60 years. You'll be rewarded with a nice crop of tasty, medium-sized berries by not allowing the bed to become too thick. An extremely vigorous variety, Sparkle is an excellent choice for home gardeners and pick-your-own operations in northern climates. Heirloom quality - recommended for beginners.
