merely a matter of self-education. for example, these lovely red bushes i hate because their touch sends a wave of horror through me, their prick, are japanese barberry. they are invasive. they turn green in the woods. apparently brought for decorative plants. they're all over kirksville, but i have ended them at my place. i am pro-hosta. that's my kind of plant. want to find some red ones with white tips but dont think they exist. i hate plants that litter.
