plant galls are technically deformities. when you hear the word gall, don’t you think tumor, cyst, swelling, wart, ugliness? well, i’d like to introduce you to the willow gall, a multi-petaled little blossom on the ends of the slender whips of willow branches. it would take a lot of gall, to call these galls ugly.
