Hercules's-Club Aralia spinosa

Aralia spinosa, commonly called devil’s walking stick or Hercules club, gets its common name from the stout, sharp spines found on its leaf stalks, stems and branches. This is a large, upright, suckering, deciduous shrub that typically grows to 10-15’ tall, but infrequently grows as a small flat topped tree to as much as 35’ tall. In its native range in the eastern U.S., it is commonly found in wood margins, fields and pastures as well as a forest or natural area at edge of woods or along streams in moist woods. It has interesting compound foliage, late summer flowers, juicy black fruit and spiny stems give this shrub distinctive and unique ornamental interest. Sparse, upright, mostly unbranched, club-like branches, ringed with conspicuous leaf scars and spines, these plants are typically naked at the bottom but crowned at the top by umbrella-like canopies of huge compound leaves.

It has stiff branches at right angles and huge, compound leaves that are the largest in North America. This plant is easy to transplant and makes an excellent addition to a pollinator garden.
