G. Frederick Schwarz, Forest Trees and Forest Scenery
“ The foliage of the tulip tree is, in truth, one of its principal points of beauty, and is inferior only to the stateliness of its form. The opening leaf-buds are conical, exquisitely modeled, and of the tenderest green. The leaves unfold from them much as do the petals in a flower, but quickly spread apart on the stem. As they grow larger they still preserve their light-green color, but take on a mild gloss. They are ready to shift and tremble on their long leaf-stalks in every breath of wind, which gives them a decided air of cheerfulness. ”
