I think so too. It looked familiar; I happened to see a gardening friend earlier who has one!! No wonder it looked familiar...lots of people here have it!
Yours is much nicer - she just has one plant. I like the way you've lined the edges with it. The leaves are so interesting too. Now I need to get a piece from her - they're easy to start as you've discovered.
I have the colorful one; there are many neat cultivars of A. ficoidea and I like them all except 'Red Thread'. Nasty thing seeded everywhere and was ugly too!
It sure should go in the database, especially since from what I read 'Snow Queen' is the only one that doesn't flower.
Glad we figured it out.
