Happy October! As Halloween and spooky season approaches, the best way to celebrate is to visit the Washington Park Arboretum and check out our sassafras. These trees are quite festive as they display leaves shaped like little ghosts (or mittens depending on your viewing angle)! Leaves can have a different number of lobes ranging from 1-3 on the same plant. This deciduous tree displays vivid colors of fall foliage in yellow, orange, red, and pink.
