You don't need a bog to grow American cranberries! Just make a well drained bed. Cranberries need an acid soil, and need to be well watered like their relatives, the blueberries.
If temperatures dip below 10 degrees F, plants need a heavy mulch to protect next year's fruiting wood. Plant one foot apart in rows two feet apart. These varieties are heavy producers of 1/2-inch red cranberries.
The small profuse flowers are reddish pink, displayed against the reddish evergreen foliage. Cranberries are a beautiful, self-fertile ground cover.
