My Tuscan Sun did ok the first year, but I moved it and it died. Melody Parfume was planted in the same adobe soil as Europeana. It never bloomed in its first year. And it looked like all its canes died this winter. But it has put out three tiny leaves.
I guess I'm such a bad gardener that I just assume the loss rate will be high. Then when something works, I'm pleasantly surprised. Iris are almost rampant here. At least by local standards. Still not sure about roses.
