Sarracenia Purpurea in Michigan Bog Garden

[Tytrapman]

Hey all, not sure if this is the correct place to post. I live in west michigan and am looking for some hardy plants I could keep in an outdoor bog garden through the winter. I found the Sarracenia Purpurea, Drosera Anglica, and Drosera Rotundifolia. Im sure the sundews wont take up much space but if I made a 24x24x12 inch bog garden would 3x Purpurea and 2 Drosera fit nicley? (buying them at medium growth) or may it not be enough plants?

I've currently got a S. purpurea that would fill the space you describe by itself. 'Of course you could keep yours cut back but they can get big.
