My friend has these flowers in her garden and she asked me for scientific name and send me these pictures. Leaves are linear, little bit spatulate in rosettes and can survive the winter which is unusual for common garden Liliaceae. I can't identify it from the picture and will appreciate any help. So what is it???
The Madonna Lily (L. candidum) has an evergreen rosette, even in Canada. My blossoms look bigger (about fingerlength) and taller than these though. If the blossoms are only thumbnail size, the plant could be a peach leaved bellflower. Campanula persicafolia.
