Rick ...
Thank you for the link. I like the fact that he reports where he collected the seeds and the elevation they were found. A geologist friend had told me that often people plant "alpine" plants that thrive at higher elevations and in other alpine areas that are never vigorous or healthy at my elevation simply because the plants don't get enough chill hours here that are found in the areas where they are native plants. That will help me as I seek the "right plants" to use on the slope.
I am also going to copy the technique Mrs. J used on another slope on my property to hold the stones in place while the plants matured. She used chicken wire to anchor the stones in place until the plants grew through the stones and wire.
I might even just use the creeping or prostrate juniper she planted on a different part of the slope because I know it has a deeper root system than the sedums I first thought about using. I know that plant works in this climate and in my soil.
I am seeking functionality more than I am looking for new plants for this fix.
I never water the junipers during the dry season and they are thriving. I don't want to be watering this part of the slope, so it's something to think about.
Smiles,
Lyn
