A stately, beautiful native plant, seen to perfection where it rears bright panicles of bloom above the ranker growth in the low moist meadows of the Ohio Valley. When we find it in the East, it has only recently escaped from man's gardens into Nature's. Butterflies and bees pay grateful homage to this queen. Indeed, butterflies appear to have a special fondness for pink, as bees have for blue flowers. Cattle delight to chew the leaves, which, when crushed, give out a fragrance like sweet birch.
