I did buy a couple of those Costa Farms DRs from HD a few weeks ago. The medium is sandy soil, so it drains OK. What I did for now is take them out of those deep pots and removed at least 2/3 of the soil and replanted them in a more shallow pot. Later on, I'll look into changing the medium to make it more chunky. I found mine on clearance for $6.98. They were out of bloom, so I don't know what color(s) they are. Will post pictures when I get a chance.
