I splurged and bought a Leucothoe fontanesiana 'Rainbow' and before I knew it, these huge plants were sprouting along side of it, eventually killing it. The guy who sold me the plant must have had Pokeweed berries in his soil. I wasn't sure what the huge plants were until recently, but with a small garden, I'm now afraid of what they'll do. Any advice from seasoned gardeners? I don't mind luring birds to my garden, but I don't want these plants to spread everywhere. Should I move them to a more secluded place at the back of one of my beds (lots of shade!). Thanks.
