I have two lilies in my garden that I don't have a name for. I have 21 varieties of Asiatic and Oriental lilies and two years ago when I replaced some that deer and drought had killed. These two bulbs were mistakenly included in my order. I didn't realize this until they bloomed last year.
We had 3 of the Lotus collection this year; Beauty (white), Queen (pale pink), and Wonder (medium pink). Ours are past their best, but I would say that yours is Lotus Queen. Here's a photo from the supplier's webpage.
