That strip between the sidewalk and the road
I know its the bane of many gardeners.
In my case, the area is about 2.5 feet wide, and there's a maple tree planted right in the middle. Its on a busy street that gets tons of salt in the winter. Its a urban area and people who park on the street will walk over it to get to the sidewalk, people will walk the dogs along it, and the trash gets put out there. I can't use mulch here, it gets washed straight into the storm drain.
There's grass trying to grow in the strip, but its not doing too well -- there's more weeds and bare spots than actual grass. The weeds I get are the tall spikey type that you see growing in the cracks of elevated highways and old parking lots. Two years ago I planted a few mint plants in the strip in the hopes that it would do the mint thing and take over. The mint is still alive, but its failing to really spread. I can't really use ditch lilies; they're too tall and I like daylilies too much to see them trampled to death. I'm thinking of trying Star of Bethlahem, which I have as a weed blocker in the back yard, but I'm not sure if it can stand the salt and the foot traffic. Does anyone have other suggestions? I'd prefer something highly invasive.
