I'm confused. I want to grow some tiger type flowered lilies in my zone 4 garden. I want to naturalize them in an area with dappled shade. There is a lot of contradicting info on the internet about these types of lilies. First, what is this class off lilies called? Then, I've seen L. lancifolium (Tiger Lily-likes full sun from what I've read), L. superbum (Turk's Cap Lily, will take dappled shade, gets tall, like 6-7 feet), L. michiganense (MIchigan Lily, native to MN, but really hard to find) and Lilium martagon (Martagon Lilies-will take shade, but I've killed a few of them already-and they're really expensive) all grouped together and it seems like some people use the names interchangably. Are my descriptions correct? I ordered some Superbum lily corms/bulbs so I'm hoping they will do OK. One other question is, will they survive a zone 3 winter? I might want to plant some at my cabin in northern MN if they are hardy enough. Is there a general rule for how deep to plant them? I was going to dig in some compost and plant groupings of bulbs like 3-5 together in a hole-will that work?
Thank you so much!!!!
