Highbush Cranberry, also known as American Cranberrybush, is a rounded shrub that grows at a medium rate, to 8-12 feet tall with dark green leaves that turn shades of red, yellow, and purple in autumn. White flowers bloom in spring and are followed by abundant red fruit loved by birds. Although tolerant of most any soil, it prefers moderately fertile, moist but well-drained soil and thrives in full sun to part shade. Problems: Insects such as aphids, scale insects, weevils, Japanese beetles, mealybugs, and treehoppers are common, while Botrytis, rust, mildews, wood rot, Verticillium wilt, leaf spots, and dieback also occur.
