Aniseroot, Osmorhiza longistylis
Apiaceae or Parsley Family
 

Woodland herb, about 2-3 ft tall with clusters of small white flowers, and fern-like leaves.  Fruits (at left) are thin pods, turning blackish, that stick to clothes.  Stem is smooth.  Blooms in mid-spring in the wooded areas, especially on the west slope.

Sweet Cicely (O. claytonii) occurs in southwest Virginia and might be found in the Park.  It is very similar, but has hairy stems and other more technical differences. Bishop's goutweed (Aegopodium podagraria) has somewhat similar leaves but looser flower clusters, and it blooms in early summer, after aniseroot has all gone to fruit.
