Lynn, the big table garden needs a work over too. My worst enemy is moss as it really takes over. I think what I'll do is replace the soil all around the four edges and replant with new stuff. The "Stinky Maple" is doing ok but the Snow Bell tree, well, I accidentally let it go dry and all of the leaves withered. It is done for the year but this has happened before so I think it is ok for the future. Otherwise I will replace it with something not so sensitive to a little drought.
The little alliums you gave me a few years back do great and return each year
. The Delosperma nubigenum is a favorite of mine. It now has hangage almost to the ground! Other "hangy" perennials are doing ok too! My backyard next door neighbor gets to enjoy those views as they are not seen from in my yard unless one walks around and then only seen close up. My neighbor can enjoy the view from his patio.
The smaller little garden-on-a-rock that visited your placed isn't too bad. I need to add something to the top because the Sedum anglicum is gone. It was so pretty in bloom!
