If you’ve gone walking recently in Crum woods (or really in any park in Philly, like the Wissahickon), chances are good you’ve seen Aralia spinosa, Devil’s walking stick. This native shrub is best known for its massive, spiky, compound leaves, and thorny stems. The leaves on Devil’s walking stick are actually the largest compound leaves in North America! It grows on the edges of woodlands or fields and along stream beds in part shade or full sun. Its showy white flowers bloom in late summer, and turn into compact clusters of black berries, making this plant attractive to birds and pollinators. 

Devil’s walking sticks are easy to transplant or grow from seed. It has few pest or disease problems; however, it does self-seed rapidly, so if you add this to your garden, keep an eye out for the seedlings or you will soon have a nice thicket of Devil’s walking stick. Photo credit: E. Hollo
