Tee...your pics are gorgeous! I bought some creeping phlox yesterday at Walmart. I've never been a dumpster driver at stores, but let me tell you what happened to me at Walmart. A lady started cleaning up plants that looked a little sick (needed water) and then she placed the ceramic planters they were in on a cart and told the checker to give them away to people that were buying gardening items. Naturally, I had a cart full of plants already, so the guy told me to get all the pots I wanted. I didn't want to look like a pig, but I did get 6 of the pots. Then as I'm leaving, the lady was dumping plants into a garbage bag. I ask if I could have some of them. She said to take all I wanted. I ended up with 6 - 3" containers of Kalanchoe blossfeldiana 'Flaming Katie' and two begonia's 6" pots (not sure what color). I gave the begonia's to my daughter. I had already bought a large Kalanchoe for her, so I kept the small ones. So, from now on, I many be checking their dumpsters...
They don't water the plants like they should, so if they wilt, they throw them away. Dumpster time for me...I'm not too proud that I can't look for a sad little plant to nurture.
