Wow, Cas, that's one of the most beautiful and full clematis plants I've ever seen! The shade side of my garage photo gets so overgrown with impatients by the end of summer, they almost cover the other plants. I always add potting soil when I plant new stuff, and over the last 5 years, I guess enough have died and enough potting soil added that it's ideal now. Plus, since I don't have any shade in my yard to speak of, even the north facing side gets late afternoon sun in the summer. I put impatients under the drip line of my big white pine tree, and they were gorgeous, too! I always wait until I get a 6 or 8 pack for about 50 cents, then buy a bunch. LOL Love this post!!!
