Hoary Mountain Mint,

Pycnanthemum incanum,

Out of all the mints commonly found along temperate forest’s edge, when in bloom, this is perhaps the showiest. The upper leaves closest to the true inflorescence will begin to turn a lighter blue color and will be much more densely pubescent than other leaves with snow white hairs, acting as a floral bract. The bracts almost give the appearance that someone may have came by and spray painted the tips of the plant white. 

Many members of Lamiaceae are wonderful nectar species, I.E. pretty much any Monarda sp. that you can think of; with that said, you can most likley associate this species with many different butterflies and a good amount of moth species.
