Dear Rick, Not sure of specifics, but I think L. squamigera is the hardiest of the genus so survival in MN seems likely. Both chinensis and longituba are definitely less hardy, but if planted in a protected spot and perhaps deeper, you mgiht have better results. Now is a good time to dig and plant deeper. Good luck Jim W. On Aug 19, 2016, at 9:05 PM, rrodich@juno.com wrote: Here in zone 4 just west of Minneapolis, L. squamigera is the only one that does well. I've had plenty of rain throughout the season and bloom is normal. I still have one L. chinensis that peaks out in the spring with several 8-10 inch leaves, surviving for seven years with only a few inches of mulch. This is the last of several I received from James Waddick. (Never bloomed, not surprisingly) I also have several L. radiata here, never able to really cope with the whacky climate here compared to what it needs. But they are still here, just surviving, unprotected in the ground for eleven years. Five plants, out of about 20 original bulbs.
