Alice Morse Earle,
Old-Time Gardens, Newly Set Forth
“ It doesn't seem hardy enough to be a wild thing; how could it make its way against the fierce vines and thorns of the forest when it hasn't a bit of woodiness in its stems and its leaves and flowers are so tender! I cannot think any garden perfect without it, no matter what else is there, for its delicate green Rue-like leaves lie so gracefully on stone or brick walls, or on fences, and it trails its slender tendrils so lightly over dull shrubs that are out of flower, beautifying them afresh with an alien bloom of delicate little pinkish blossoms like tiny Bleeding-hearts. ”
