In my own neighborhood “wild” = “neighbor’s flowers escaped and living off the land”…. Examples of the voluntary expats include raspberries (I now harvest enough every year for a double batch of jelly), English ivy, green and yellow variegated bamboo (a chunk was handed off to another neighbor recently), orangey yellow African daisies, buttercups hop-scotching their way through the flower beds, and a variety of deep purple hollyhock that vigorously self-sows. There’s honeysuckle popping up along the fence-line (though the original bush was dug out by the landlord after his rentors moved). I have wild roses popping up in the lawn alongside the house (but those are my own fault.) And there’s something that we kids used to call “tobacco plant”– pleasantly orangey/yellow now, deep red-brown in fall– and dangerous if not vigorously pulled. The truly wild? nettles. non-native blackberries (yum) and more rarely a native variety, salmon berry, ocean-spray and — a prominent ex-pat — scotch broom.
