That looks wonderful - and you have me looking to see if something like this is able to tolerate life in the Pacific Northwest!!!!!!
If you find that it can tolerate it, let me know. I can harvest some bulbs for you.
Pacific NW girl here... I have this coming up in a flower box and have NO recollection of planting it! It's lovely... : )
