Gardeners' Notes:


On Jul 18, 2016, coriaceous from ROSLINDALE, MA wrote:

Flowers are white with wide crimson centers.

Blooms mid-late July. Secondary buds extend the bloom season to about 4 weeks.

According to B&D Lilies: "We believe this lily was actually bred in Canada by Wilbert Ronald and Lynn Collicut while working at the Mordon Research Facility in Manitoba. For years, debate has raged among members of the North American Lily Society including discussions on how to do genetic testing to prove who it really belongs to."

AKA 'Friso'.

Hardy in Z5-9.
