I found these two flats of ground covers. From chartreuse to sage greens and purples; I don't even know how many different kinds of plants there are. The instructions say you can lay down the whole sheets or cut them up into 5 inch squares to put down. They are growing on a layer of coir, or coconut husks. I wish I had room on the walls (brick) as I can see them as a vertical garden.
Supposedly, you can fill in areas or even put out in the lawn as they can be mowed over. I am such a sucker for new things and am trying to figure out where to put them. I just love these.
