An article in last July's Pacific Horticulture about Luther Burbank's work on Lilies mentioned almost as aside that Burbank successfully crossed Lilium pardalinum and Trillium ovatum, although he was unable to propagate the offspring. If I didn't actually gasp, I at least whistled out loud when I read this, it seemed so unlikely. Further internet research has reinforced my doubts, as I tracked down the following chromosome counts: Lilium pardalinum 2n=24 Trillium ovatum 2n=10 I don't see how such a cross would have been possible, but I have a feeble grasp of genetics, math, and plant breeding, Can anyone correct me?
