I'd be interested in other peoples comments re: Doubles. I haven't had any from the supplier above, but over the past two years have had 6 different doubles from several reputable vendors (one I even purchased a pack of 3, which I rarely do). I have yet to have one successfully bloom. Most aborted early in the bud stage. My three bulbs of Davyd grew beautiful plants (4'), full of nice sized buds. Two buds opened deformed (not double, but deformed), the others just sat on the plant for three months and slowly withered without ever opening.
I'm not keen on the doubles, as they don't look like lilies to me. If they were called something else, I'd be okay...LOL, but lilies are supposed to have 6 petals. My DH kept asking me to get a few doubles, but I won't waste any more $$$ on them this year...Anybody else having success?
