Introduction to Cherrybottom
Cherrybottom Park is a 40.78 acre stretch of woodland that hugs a curve of Big Walnut Creek. Unlike its neighbor, Blendon Metro Park, Cherrybottom is largely unmaintained and unfrequented, no doubt in part to the muddy and brambly environment characteristic of riparian floodplains. However, to myself and friends, the park is a favorite place to visit for spring ephemerals, foraging, and immensely scenic views if you venture far enough into the swamp.
Poison Ivy
Poison ivy has compound leaves with three leaflets. The middle leaflet has a longer stem than the other two whose stems are inconspicuous. The leaves are alternate on their vine, which grows hairy when older.
Boxelder leaves are similar but opposite in arrangement, and wild strawberry leaves are similar but consistently serrated.
