Jerusalem Artichoke, Helianthus tuberosus
Asteraceae or Sunflower Family


Tall sunflower, to 6 to 10 feet tall. Flowerheads about 3 inches wide, with about 8 to 20yellow rays, and a cluster of daker yellow disc flowers. Green bracts behind flower long-ponted. Stems hairy. Leaves opposite each other, egg-shaped and coarsely toothed. Blooms in late summer to fall.

A handsome native, but also cultivated, both as an ornamental and for the edible roots, so sometimes also escaping. In Wildwood, occasional mixed in with the other yellow sunflower-like species so common in the summer and fall.

The many yellow sunflower-like species in the Park are not easy to tell apart, but the other species in the Park have smoother, less rough hairy-stems.
