Crinum in MO

How deep should the crinum be planted to avoid frost killing?  It looks as though they've evolved a long neck to permit them to tolerate being planted deep.

I have a small bulb of SuperEllen and one of its sister seedlings whose name escapes me at the moment and I am willing to put them out to 'naturalize' in my yard, but I don't want to plant them too shallowly.  I had a crinodonna freeze to death on the north side of the neighbor's garage and I wouldn't like to have either of these two bulbs experience that fate.

Do you have them next to a foundation or in a sheltered location in any way, and do you cover them over with a blanket of insulating leaves in the fall or anything similar to limit frost penetration into the ground?

As long as people are thinking about this, how about Agapanthus?  Any recommendations on getting them to thrive outdoors in the ground in a Connecticut garden?
