Vaccinium corymbosum seed
The most widely grown blueberries are cultivars of northern high bush blueberries (Vaccinium corymbosum), branching mainly deciduous shrubs reaching up to 1.8m (6ft) in height. Apart from producing fruit they are ornamental, producing bell-like flowers in spring. The foliage has good autumn colour. Half-high blueberries are hybrids between Vaccinium corymbosum and low-bush Vaccinium angustifolium, making more compact plants.
