Hi Jim,

You mentioned that you use a cold frame for marginally hardy plants like the L. aurea.  Could you tell us about its design or point me to the archive if you have already done so?  I'm also in zone 7 and am thinking of building a cold frame for things that won't survive outside unprotected but wouldn't do well in my tropical greenhouse.

Is the cold frame vented automatically somehow, or do you prop it open on sunny days?  Are the plants only housed in it during the winter, or does it keep the rain off dormant plants in summer?  Are the plants in pots or in the ground?  

Thanks,
Nick
