Columbine (Aquilegia canadensis) of the buttercup family is an endangered flower. Enjoy with your eyes. Protect it.

Toothwort (Dentaria diphylla), also called pepperwort, is a lovely low-growing plant in the mustard family. Bite a leaf if you dare; they bite back!

Dog violet (Viola conspersa) flowers make a lovely snack while walking in the woods.

Gaywings (Polygala paucifolia), also called fringed polygala, is a rare delight in the late spring forest. Protect it.

 Black cohosh (Cimicifuga racemosa, now Actaea racemosa) flings its black hands into the light just as the leaves are emerging on the trees. (Wait until the early winter to dig roots, if at all. This plant is at risk of over-harvesting. ) It is part of the dangerous, poisonous, buttercup family.
