This lily grows and blooms wonderfully for us. Martagons and their relatives seem to be the lilies that chipmunks like LEAST to eat, thank goodness. It's also very beautiful.

It's done well here in spite of being at the southern end of its preferred climate range. According to Old House Gardens this is an early-20th-century cross of L. martagon and L. hansonii.
