You Can’t go Wrong with Phlox, Maybe
Phloxes are great plants but there still are still a few things to watch out for. Some are susceptible to powdery mildew and benefit from good air circulation (i.e., not crowding them too closely with other plants). Some reseed readily and you might end up with more than you want. For me, woodland phlox has re-seeded gradually to fill out an area nicely but not aggressively. It does pop up in my lawn near its garden bed, but that doesn’t bother me. I’ve heard some people complain that their garden phlox re-seeds profusely and they have to pull out extras every year or two. They must have better conditions for it than I do, because mine so far hasn’t done that. Anyway, they are not hard to pull up, and you can probably find takers for extras of such a pretty plant. Creeping phlox, as discussed, spreads out through runners on the ground and makes a nice ground cover. If you want a plant doesn’t go anywhere at all, this may not be for you, but it is also easy to pull if you end up with more than you want.
These cautions are all quite minor, so if you want to help out hummingbirds, butterflies and moths, and bees to boot, go for some phloxes!
