The cultivated cultivars of the low blueberry (Vaccinium angustifolium) and the medium blueberry (V. angustifolium and V. corymbosum hybrids) come from the species growing in the forests of the north-eastern part of the United States and the south-western part of Canada. The Vaccinium angustifolium species is a small shrub with very tasty blueberries, 6 mm in diameter. Nowadays, they are still picked on a commercial scale in their natural habitat.
Both the low and medium blueberry requires similar soil conditions like high blueberry, i.e. regulated air and water conditions, sour soil and increased quantity of organic matter, however, it seems to be considerably more tolerant to higher pH and heavier soil. It is perfectly suitable for cultivation in small home and allotment gardens and in containers. On commercial plantations, thanks to dense planting, it yields a good crop. Its fruit, although slightly smaller, is as attractive and precious as the fruit of the high blueberry.
The half high blueberry cultivar, introduced to cultivation in 1996.
Grows into a compact shrub with a rather erect habit, reaches the height slightly above 0.8 m, up to 1 m.
Average size or big berries, pale blue in colour which is tasty and very sweet when fully ripe.
Highly valued because of the cold hardiness, regular shrub shape and use for container cultivation.
Cold hardiness -37°C (USDA – zone 3).
V. angustifolium and V. corymbosum cross. Bred at the University of Minnesota in 1986.
Grow up to 0.45–0.60 m height.
In the autumn its foliage changes colour into exceptionally deep red.
Develops fruit 1-1.1 cm across, with a small pedicel scar, aromatic and very tasty.
One shrub yields a crop of 1-2.5 kg.
More tolerant of unfavourable soil conditions.
V. angustifolium and V. corymbosum hybrid. Bred at the University of Minnesota.
Grows up to 0.6-1.2 m high.
Develops dark blue fruit 1.25 cm across. They can be kept well after chilling.
Gives high yield crop from one shrub 1.5-3.5 kg.
Tolerant of unfavourable soil conditions.
An early cultivar. Introduced to cultivation in 1996.
Develops shrubs of average size, up to 1.2 m high, with an erect habit.
Berries very tasty, exceptionally aromatic, pale blue, average size.
Attractive due to its cold hardiness, regular shrub shape and use for container cultivation.
Ornamental and practical dwarf cultivar. V. corymbosum and V. angustifolium hybrid.
A low shrub, only 0.5 m high, ball-shaped habit.
Its leaves are small and shining.
It blooms profusely in the spring, displays flowers of white colouring.
Average size berries, pale blue in colour.
Thanks to an interesting shape 'Top Hat' is suitable for landscaping and for cultivation in pots.
Hardy, undemanding cultivar. Cold hardiness –37°C (USDA – zone 3).
