Edible wild blueberries are a treat for any backpacker hiking or camping in Colorado. Ultralight backpackers pack even lighter when they know there will be berries to eat. For many, gathering wild food is an important wilderness survival skill. But, with numerous poison berries out there, it is important to know whether a blueberry is edible. There are four main types of blueberry bushes; knowing how to spot them will make the difference between getting sick or enjoying delicious blueberries.
Identify highbush blueberries by their large size, with bushes often growing 6 to 12 feet tall.

The stems are woody, and the bushes grow evenly rounded. The dark, shiny green leaves are 1 1/2 to 3 inches long and have a tough, leathery texture. In the fall, the leaves turn bright red.
Spot hybrid or half-high blueberry bushes by their 2- to 4-foot height and medium-size fruit. These berries are able to grow in the colder, higher climates of Colorado. They have a sweet flavor, and their leaves turn red in the fall.
Identify lowbush blueberries by their low growing pattern, with bushes 1 to 2 feet tall, , according to the U.S. Highbush Blueberry Council. Lowbush blueberries look more like ground cover than bushes. They like to grow on rocky outcrops as well as in bogs or swamps. Lowbush blueberries have hanging, white, bell-shaped flowers in the spring and bunches of blueberries dusted with white powder in the summer.
Identify rabbiteye blueberry bushes by their height. This bush grows up to 15 feet tall and is found in the warmer climates of Colorado.
