There is always someone in my class who wants to munch on anything we come across. Here's a collection of various red fruiting plants.
What is most interesting about the plant is its reproductive biology. With most plants, when a flower is fertilized, it becomes a fruit. In Partridgeberry, there is a pair of white tubular flowers, BOTH of which must be pollinated to produce the fruit. Here you can see the two holes where the flowers once were.
Serviceberry, Juneberry, Shadbush, Shadrack. Amelanchier arborea. Ripening in June, the fruit is used for jams, pies, wine, or eaten right off the tree. Depending on your palate, the taste is described as having hints of blueberry or cherry.
The folklore behind the names is interesting. In the old days when the ground was frozen during winter, people could not dig a burial pit. When serviceberry came into bloom early in the spring, it told people the ground was thawing, and services could then be held for the dead. When this plant started blooming, it indicated to people the shad were running, and it was time to go fishing.
While I haven't mentioned this for each individual species, the vast majority of these are used by birds and mammals. Wildlife students learn which of these are native or exotic, which prefer forests or open fields, and management is practiced accordingly.
