Entering my second year from just 10 bulbs planted last year. So far this spring I have counted 17 stalks growing with more possibly on the way! Great multiplier, blooms last a little over a week, blooms two to four times but stays green and glossy after flowering. Not especially fragrant, but adds beautiful yellow color.
In my mind one of the very best asiatic lilies available.
Contrary to many of the images uploaded for this lily, Grand Cru MUST have dark red markings at the base of the leaf with spots on the lower 25% of the petal. A solid color yellow lily is NOT grand cru.
It has upfacing bulbs and the buds are outstanding just before they open.
