Companion Plants for a Zone 5 Peat Bog Garden

A gardener building a 2-foot-deep lined bog (washed sand + sphagnum peat) in Zone 5a with ¾-day sun asked for companion plants for Sarracenia and Venus flytraps.

Carnivorous Companions

• Hardy sundews: Drosera filiformis, D. intermedia, D. rotundifolia; possibly D. binata 'Giant Staghorn' (survives potted in Oregon winters).
• Hardy butterworts: Pinguicula vulgaris, P. macroceras, P. grandiflora, P. caerulea—plant in light shade of taller Sarracenia.

Non-Carnivorous Bog Natives

• American cranberry (Vaccinium macrocarpon)
• Bog blueberry (Vaccinium uliginosum)
• Cinnamon fern (Osmundastrum cinnamomeum)
• Bog orchids (watch for invasiveness)

Special Addition

With a drip/trickle water source, Darlingtonia californica (cobra plant) can thrive.
