Ashley,I think Ian was saying that it is a seedling of 'White Beauty', not that it actually is that. 'White Beauty' is obviously a particular plant selected for certain qualities..... so the offspring could be quite variable. It all depends on what the parentage of WB was like. I think one of the main things for WB is that it offsets readily, making it a viable commercial plant. Given Stephen's plant has offset into a large clump it has inherited this trait from it's parents, making it more likely that something like WB was the parent. Or at least that is how I read Ian's comment anyway.
Re the discussion of E. 'White Beauty': a botanist at our local university is a specialist in Erythronium and after examining a patch of 'White Beauty' concluded it is pure E. californicum with no trace of hybridity. The usual wild form does not have the rounded petal tips of White Beauty', but that's not a botanically significant characteristic.
