Other info. - This small, shrubby species is common in the lower 1/2 of Missouri. The plant produces a tasty blueberry in the summer which is enjoyed by wildlife as well as people. The plant is distinguishable from the two other Missouri blueberries by the fact that it is the smaller of the 3 species, it has leaves which are glaucous below, and the stems are typically mostly herbaceous and some shade of green. The other two species of Vaccinium in Missouri become woody very early on in their growth.
