Blueberry Echo is heads above the rest when it comes to double cropping. The berries begin to ripen early in the blueberry season before other varieties bear fruit. Then, more blueberries appear in early fall, producing an even larger crop. This late fruiting continues until frost. You will have fresh, home-grown, sun-ripened blueberries for weeks. Echo is also very ornamental, having a compact habit and blooming twice a year. Growing up to 5 ft. Tall, Echo has a compact habit and flowers twice a year. Its spring foliage emerges lush green with a red blush before turning a lustrous, dark green. It can be grown in the garden, as a hedge or in patio containers.
