I had the same experience as mentioned above. I had planted several of these bulbs and most of them came up as this species. A few flowers turned out to be larger and less recurved. I think they may be the "Uchida" cultivar of this species. They are however just as beautiful.

my rubrum planted in late spring 2003, blossomed in september. in 2004, the 2nd year, it surprised me by sending up a second stalk and producing another set of beautiful blossoms, blooming in september as well. i can't wait to see what 2005 has in store for me.
this is the last lilium to blossom in my gardens.
i adore the small, recurved, pink, white and red down-facing, "smelly" & "heady" blossoms.
