I have this weird strip on the sidewalk. Part is damaged sidewalk but the thin strip was actually left by the city either originally or after some sort of work. The issue is that it has to be mowed/weedwhacked. If I cut it out completely, it turns into a muddy mess when it rains (and all winter!). So, I'd like to strip it, and replace it with a groundcover...preferably evergreen. It would need to be heat tolerant, salt tolerant, and somewhat tolerant of foot traffic and dogs. Preferably lower in height. Does such a plant exist?

I've tried various thymes in a spot like that and found them difficult. Same with low growing sedums. I finally hit on a winner with Smooth Rupturewort (Herniaria glabra) - evergreen, drought tolerant, takes some foot traffic, stays low but also spreads out quite quickly. It doesn't get much in the way of flowers, I think some rather inconspicuous greenish ones in the fall. Also easy to propogate, I've been just pulling hanks out and jamming them where I want more. I have mine in full and part sun, plan to try some in deeper shade to see how they do.

Just looked up this plant. Sounds like a plan! Thanks!

Received my Hernaria glabra seeds in mail today. Has anyone grown this from seed? Should I start it now and hope it grows enough to get through the winter or wait until Spring?

I got mine as little 4" pots in early spring, split them into 4ths, and popped them in the ground. They did quite well, spreading out nicely the first year. Since you are in a colder zone than me, I might wait until early spring to start them myself. Do you have a greenhouse? I don't, but it seems that often helps with the early spring seeds. I just have a sunny southern window for my feeble attempts at starting seeds.
