Expanding a Zone 6 Outdoor Carnivorous Bog Garden: Species Selection and Winter Mulching

A Rhode Island landscape architect (zone 6, SE exposure, mulched 12" pine + 8" oak) successfully overwintered S. purpurea, 'Scarlet Belle', S. rubra, S. flava, D. filiformis, D. rotundifolia. Asked what else to add.

Possibilities

• Any North American carnivorous plant, including flytraps.
• Darlingtonia: challenging; summer heat tolerance determines success. Read care sheet first.
• Butterworts: Western (P. macroceras), Canadian (P. vulgaris), European species overwinter easily but need summer cooling.
• Southern butterworts (P. primuliflora, etc.) prone to fungus under mulch; best grown as annuals in cold climates.

Sourcing
