Why Cephalotus Cannot Overwinter in Zone 7 Bogs: Temperature Requirements and Indoor Alternatives

Why Cephalotus Cannot Overwinter in Zone 7 Bogs: Temperature Requirements and Indoor Alternatives

Cephalotus is warm-temperate (hardy to Zone 9). It tolerates brief 27°F frosts if roots don't freeze, but Zone 7 winters are too cold.

Mulch Doesn't Prevent Freezing

Mulch only slows temperature swings—it doesn't stop freezing.

Recommended Approaches

• Grow indoors on a very sunny windowsill year-round.
• Grow outdoors in season; overwinter in a cool greenhouse (35–55°F).

See care sheets for details.

Good growing!
