Rosemary is great. I was sad to say goodbye to my old crawling Rosemary plant at my old house. I have two of them planted in the front garden here, and hopefully summer won't kill them off. Hopefully, also, they won't entangle themselves with the various services (electrical, Internet, water, sewer) buried nearby, underground. :P
I have an old one outside, it was cut back and is not growing that well since. But enough to harvest from time to time, even just a little bit. Do they have such a vast root network that they can do damage to those lines? I didn't know that...
I don't know either, but I don't want to risk it and find out :P
Also, find round Any local war memorial...
