I live in Michigan, Zone 5. I found 3 bags of bulbs that were forgotten. They're all sprouting. Heavenly Bluebells, Purple Drumsticks and Super Color Hyacinths. Can I save them? Can I plant them? The research I've done is contradictory. Also, I have a bag of New Tiger Lilies. These are July - September bloomers. Not sure if I can plant them now.

Plant them! Now! :-)
In my experience, you could probably plant the Tiger Lilies now but they may not bloom till next year (I planted some in the middle of summer a few years ago and it took until the next season to get blooms).
