The only one I found is S-W gardens in southwestern :Ontario. But she is sold out for this season. Maybe you could put an order in for next year with her. Bulbs can be shipped across the border.
You could also try the NALS, or some of the state lily societies to see if they mention a source

Thank you! I shall look for the website (assuming there is one) and save it for future reference.

Hi - here is the link for her garden. They grow nice lilies, and I would expect everything you get from them to be true to name.

Here is a link that might be useful: Sandra-Pat's Garden

Duly bookmarked, and thanks again!
