These flowers are tiny. I have no clue what plants 3 and 4 are. We are letting 2-4 grow in the community garden bed for now; I'd hate to get rid of it only to find that it's something useful. I told my mom I knew 2 wasn't a weed but I wasn't sure about the others. Then I told her I'd ask my gardening friends online and they would probably know!

Thank you for you answer and time! Mystery Solved!

@Woodstock Mary...you don't say where you live, but there has been work (mostly by the renowned Dr Michael Dirr) to produce more hardy lantanas. Of course there is the old reliable Miss Huff (Z7-ish), but I'm not fond of the color combination in that one. It IS hardy for me...most winters, lol. Someone near me grows it on a steep bank, and theirs seems to do quite well even when mine doesn't. I think the key is superb drainage. But it seems like it takes mine a long time to make headway, even after a mild winter. What Dr Dirr has done is produce hardier varieties in multiple colors. The original was 'Chapel Hill Yellow', which I've grown since it was first released several years ago. It's still the prettiest to me, a pure, light yellow with no secondary colors. It's not *quite* as hardy as the followup varieties 'Chapel Hill Gold', ' Chapel Hill Apricot Sunrise', and 'Chapel Hill Sunny Side Up'. I've heard there's a mostly white one, but I haven't been able to find it. All of these are a good zone hardier than the old cultivars. Two other varieties I've seen but not tried are 'Sonset' and 'Mary Ann'. 'Sonset' is a classic yellow and orange; 'Mary Ann' is yellow and pink. I've seen them both at my local nursery. I *think* 'Mary Ann' is produced by Monrovia, so you should be able to find it. I know Plant Delights sells 'Chapel Hill Yellow', but they're kind of pricey, lol. I do love their selection of perennials, though. The other Chapel Hill types I've just run across at my local Home Depot and Lowe's. I don't think I've ever seen them for sale online, but a Google search would be worth it. Good luck with your lantana. They ARE variable in hardiness, so you might get lucky ;) John EDIT: I forgot to say that lantanas are very easy to root from cuttings. I ALWAYS take a couple of late summer cuttings of all the types I grow, just in case. I overwinter them inside on the window sill (along with salvias, begonias, brugmansias...you should see my window sills in winter. Then again, no, you shouldn't, lol). Some years I need them, others, I don't. Better safe than sorry.

Yes, agree Achillea ptarmica, Most likely A. p. 'The Pearl'
