Blueberries are flowering plants of the genus Vaccinium with dark-blue, -purple or black berries. Species in the section Cyanococcus are the most common fruits sold as "blueberries" and are mainly native to North America[1]. They are usually erect but sometimes prostrate shrubs varying in size from 10 cm tall to 4 m tall. In commercial blueberry production, smaller species are known as "lowbush blueberries" (synonymous with "wild"), and the larger species as "highbush blueberries". The leaves can be either deciduous or evergreen, ovate to lanceolate, and from 1–8 cm long and 0.5–3.5 cm broad. The flowers are bell-shaped, white, pale pink or red, sometimes tinged greenish.

 

The fruit is a false berry 5–16 mm diameter with a flared crown at the end; they are pale greenish at first, then reddish-purple, and finally blue on ripening. They have a sweet taste when mature, with variable acidity. Blueberry bushes typically bear fruit from May through June though fruiting times are affected by local conditions such as altitude and latitude.

O mirtilo, também conhecido como arando ou uva-do-monte, ou até blueberry (Vaccinium myrtillus) é um arbusto que pertence à família Ericaceae (família da azálea). As plantas são arbustos de pequeno porte que crescem em sub-bosques de florestas temperadas na Europa. Vive em regiões nas quais o inverno é bastante rigoroso, daí a dificuldade em cultivá-lo no Brasil.

Em Portugal vive em regiões nas quais o inverno é rigoroso, porque necessita em média de 500 horas anuais de temperatura entre os 10º e os 12º celsius. É na zona do médio Vouga, no vale do Rio Vouga que se encontra o local ideal para a produção deste fruto, nos concelhos de Oliveira de Frades, Sever do Vouga, Águeda e Albergaria-a-Velha, sendo Sever do Vouga o que reúne as melhores condições.
