About Small cranberry
Vaccinium microcarpum, also known as dwarf cranberry, is a small, perennial creeping shrub belonging to the Ericaceae family, notable for its tiny leaves and small, edible red berries. It forms a dense and attractive groundcover, ideal for rock gardens, alpine gardens, or as an understory plant in cold climates. Its fruits are valued for both their taste and ornamental appeal.
Native range
North America and Eurasia
Care tips
It requires full sun to partial shade and a very acidic (pH 3.5-5.0), moist but well-drained soil, rich in organic matter. Watering should be consistent to maintain substrate moisture, especially during fruiting, preferably using rainwater or demineralized water to avoid salt buildup. Avoid alkaline or limy soils, as they are fatal for this acid-loving species; an annual amendment with peat or specific ericaceous fertilizer is beneficial.
