Lucy,

I grew oriental lily 'Montana' several years ago but lost it to a particularly harsh winter. It made me sad because it was my favorite oriental lily. If I remember correctly, it had larger flowers than 'Casa Blanca', and they were a pristine white with a bright yellow throat and lots of deep purple-red spots. Very fragrant as well. It also had very tall stems with more flowers per stem than any oriental I've ever grown--so many that it becamse top-heavy and usually needed staking, though it was well worth the extra effort.

I think that the word "white" after the cultivar 'Montana' was for descriptive purposes and not part of the name.

Lily 'Montana' is very hard to come by and I have not been able to replace mine. If you do purchase it and decide in the future that you'd be interested in trading, I'd jump at the chance!
