Cranberry, Vaccinium macrocarpon, is a well-known berry native to the cool bogs and wetlands of North America, where it has been harvested and used for hundreds of years. Indigenous peoples traditionally gathered cranberries for food, dye, and medicine, often mixing the fruit with dried meat and fat to make pemmican, a long-lasting energy food. Cranberries later became a valuable crop in colonial farming and are now grown commercially throughout the United States and Canada, especially in cooler regions.

Cranberries are highly nutritious. They are rich in vitamin C, vitamin E, manganese, dietary fibre, and powerful antioxidants such as proanthocyanidins, which are well known for supporting urinary tract health. The berries are low in sugar compared to many fruits and have a tart, refreshing flavour, making them ideal for juices, sauces, jams, baking, and drying. Fresh berries are quite sharp eaten straight from the bush but mellow beautifully when sweetened or cooked. Leaves have also been used in herbal teas traditionally, though culinary use focuses on the fruit.

Cranberry plants form low, trailing evergreen vines with small glossy leaves and delicate pink to white spring flowers that mature into firm red berries. They naturally grow in acidic, peaty soil and prefer cool climates with consistent moisture. Although they are long lived and hardy once established, cranberries grow slowly and take patience, often taking several years to reach full production. However, their ornamental quality, edible berries, and evergreen nature make them a lovely long term addition to a home garden.

How to Grow From Seed:

Cranberry seeds require cold stratification to germinate well. Mix seeds with moist sand or paper towel, seal in a container, and refrigerate for around three to four months. After chilling, sow into a shallow tray of acidic seed raising mix such as peat-based compost.

Do not bury deeply, simply press the seed onto the surface and lightly cover. Keep moist and place in a bright but cool position. Germination can take several weeks to a few months. Once seedlings are large enough to handle, transplant into individual pots and continue growing in acidic soil, keeping moisture consistent.

Cranberries are best grown in containers, raised bog beds, or garden beds with reliably damp conditions but never waterlogged. An old bathtub or trough would be perfect! Full sun to light shade is ideal. Plants generally begin to bear fruit in their third or fourth year, rewarding patient gardeners with glossy red berries for many seasons.
