As for the wayside flowers, they are, as becomes the place, of the very commonest and most old-fashioned sorts, more welcome to my eye than the choicest of rarities: golden-rods and asters in great variety and profusion, hardhack and meadow-sweet, St. John's wort and loosestrife, violets and anemones, self-heal and cranes-bill, and especially the lovely but little-known purple gerardia.
"A Rambler's lease"

Asters of imperial purple, golden rod fit for kings' scepters, march along with her in ever thinning ranks; the great bindweed covers fences and clambers up dying cornstalks; and in many a covert and beside the open ditches the gerardia swings her pink and airy bells.
