Sarracenia purpurea ssp. purpurea in Zone 9: Dormancy Adequacy and Large Pot Soil Mix

Dormancy in Southern California

S. purpurea ssp. purpurea prefers sub-20°F nights but grows fine in Zone 9 (high 20s°F nights, low 50s°F days). Northern growers get larger plants, but yours will thrive.

Species Comparison

• Largest rhizome: S. oreophila
• Fastest division: S. rubra

15-Gallon Pot Mix

Use peat + perlite (equal parts). Perlite is vastly lighter than pumice or sand (4 cu ft = 34 lbs vs. 450 lbs for sand). Moving 15-gal pots is manageable with perlite. If unavailable, peat + pumice (equal parts) is acceptable.

Good Growing!
