Bog Garden in New England

[jeffnboston20]

I am considering starting a bog garden or two - with plenty of pitchers and cobra lillies and anything else I (or you) can think of.

I live in Mass. - northeast corner - Zone 5

I am looking for varities that will survive the new england winter outside.

Quentions I have for you would include :

Should I build (dig and bury the large planter) now and plant - letting them winter here

or

should I do all of that in the spring

thanks for your help
