There's a florist/greenhouse in a neighboring town I like to visit each spring for their great assortment of annuals and perennials. They used to sell potted Peonies, and have a plot outside the greenhouses where they apparently planted the extras at the end of season. That plot of Peonies is what convinced me I NEED some modern named varieties- such gorgeous colors and forms, and with strong stems standing up without staking. Of course I realized this after they quit selling Peonies! LOL
Later last spring I lucked into finding Bartzella in a 3 gallon pot at Lowes for $39.95, and a few weeks later found Pink Hawaiian Coral at another Lowes for $15. That got me started, then later ordered 3 from Klehm's when they had a buy 2, get one free sale (Coral Charm, Flame, Do Tell). Both of the Lowe's plants bloomed nicely this spring, but Flame was the only Klehm selection to bloom (which was no surprise, I didn't really expect to see any bloom the first spring).
