Eastern white pine (Pinus strobus)
Native in only a few northwestern Indiana counties, plus along certain creeks in west-central Indiana; Introduced in remainder of state ornamentally and for forestry purposes. Sometimes regenerates from plantings.
This tree has a characteristic pine-tree shape with a whitish sheen to its needles. Needles occur in bundles of five that remain on the tree for two years and then are shed. Pine needles are leaves adapted to prevent water loss so trees do not become stressed in the winter when water may be frozen in the ground.
