    I have seen this Lance-leaved Goldenrod growing wild in various spots in meadows in southeast Pennsylvania and northeast Illinois. It is grouped as one of the Flat-topped Goldenrods with the Ohio and Stiff Goldenrods. It used to be classified as Solidago. Its slender, willow-like leaves give it a fine texture. It has paralleled veins on the leaves. Its native range is from Newfoundland to southern Manitoba down into the southern US. I've never seen it sold in nurseries.
