2-3 weeks. Muscadet is a nice shorter oriental lily. First season bloom time will be shorter than established lily. Bloom time has a lot to do with bud count: more buds = longer bloom time.

I also get 3 weeks out of Muscadet blooms.

I can get 3-4 weeks of bloom of time. I have Muscadet planted with Casa Blanca. The Muscadet blooms first for about 3 weeks. Then the Casa Blanca starts and the 2 overlap for about a week. Then Casa Blanca continues for another 3 weeks. I love this combo because I get 7-8 weeks of lily blooms. I'm in zone 5 northern Indiana. My bulbs came from Brent and Becky's Bulbs. Times are for year 2 of the bulbs. I'm hoping for even more this year!
