Giving up on my rock garden..
I started a rock garden a few years ago. It borders the street and gets snow and sand and road salt piled up along the edge on one side.
I bought all new plants last year including a mini geranium, sempervium and sedum, pink thrift, phlox subulata, rockcress, snow in summer, an elfin thyme and a few more that I forget.
This spring, very few of my plants survived the winter and the ones that did look horrible. One phlox looks pretty good, one is pretty bad. The geranium came back but hasn't grown as vigorous as last year. A sedum Vera Jameson came back but it is a little further away from the street than the others. Everything else is dead.
Are there any plants that I haven't tried that will tolerate the sand/road salt along the edge? That are hardy in zone 5? I would really like something that is really dependable and grows vigourously without being invasive.
Thanks for any help you can offer..
