Blueberries are fruiting plants of the genus Vaccinium (along with cranberries and bilberries). They have dark blue berries, and most species are native to North America.
The plants are perennial, and grow well in colder climates. The berries are sold commercially, but due to yields and handling challenges, they tend to be a relatively expensive fruit.
Uses
Delicious eaten fresh, or cooked.
Can be frozen, after which they are best used cooking. Great in pancakes and muffins.
