I have purposely not grown L.superbum because of all the reports of it getting so tall. Just today I visited a North Star Lily Society member's garden. She has a Lilium superbum: it is one hefty stalk, already seven feet tall, and the inflorescence hasn't even elongated yet (all the buds are just showing clumped together at the tip).
As she was telling me about it, she mentioned that two years ago she had transplanted three bulbs from the front of the garden to the back, and she lost two of them. She said someone had told her she was risking losing the bulbs if she did any transplanting with this species, something I never would have guessed, and still wonder about.
All this said, I did break down and do have some L. superbum seedlings from Joe Nemmer's seed.
