Whortleberry pie

Vaccinium myrtillus or European blueberry is a holarctic species of shrub with edible fruit of blue color, known by the common names bilberry, blaeberry, wimberry, and whortleberry. It is more precisely called common bilberry or blue whortleberry to distinguish it from other Vaccinium relatives. Vaccinium myrtillus is a small deciduous shrub that grows 10–51 centimetres tall, heavily branched with upright, angular to narrow winged, green-colored branches that are glabrous. It grows rhizomes, creating extensive patches. The shrub can live up to 30 years, with roots reaching depths of up to 1 metre (3+1⁄2 ft). It has light green leaves that turn red in autumn and are simple and alternate in arrangement. The leaves are 1–3 cm (3⁄8–1+1⁄8 in) long and ovate to lanceolate or broadly elliptic in shape, with glandular to finely toothed margins; they are prominently veined on the lower surface. In winter, the foliage turns deep red and becomes deciduous.
