Alstroemeria

Strange time to perhaps post about these beautiful flowers but when these in a garden I work in are still flowering in December!...I had to post them. They have been flowering continuously all summer since late May. Lots of stems still emerging from the rootstock's with the potential to flower until the cold weather starts. I think if this variety was growing in milder climes, it could flower almost all year round. Unfortunately, I have no idea what the variety name is...
