Hi Lindalee--and
on your picture
I would like to ask how long have you had this lily? Do you remember where you purchased it, or was it grown from seed? You have asked an interesting question because whoever told you it was part of the Grand Canyon suite (strain) certainly has a higher than average knowledge of lilies. Park Seed Company first introduced the American Classics series back in 1995, and since then has had only limited commercial availability, mostly by seed.
If you can still get a 'face-on' picture, that would give a pretty good idea of whether it's a Trumpet or an Oriental Trumpet (Ortega). It won't be the prettiest picture--but it would tell a lot.
The original stock of the American Classic series was developed by Dr. Robert Griesbach of Wisconsin.
