You got a great deal on your irises, but that was a LOT of work too.
What I love about irises- besides their beauty & independent return year after year, is that they tolerate terrible soil & neglect-My deep purple ones had originally been planted in the side yard here by a former owner, but it was too shady & very few bloomed for years, until I moved them into my front yard along the driveway, where they get lots of sun & bloom like crazy. The soil is poor & rocky too but they don't care one bit.
It worked out great because my deep purple ones all bloom early, then I get a second wave of irises when all the other colors chime in. Some of my irises were in a big box of unknown rejects that someone cleared from their garden...freebies, so I had no idea what colors I was planting when I put them in. I'm in the mid-south btw, so the daylillies like the climate here better.
