Why Southern Dewthread (Drosera filiformis tracyi) Has a Different Season Than Venus Flytraps

Different Origins, Different Clocks

• Venus Flytrap: Coastal North/South Carolina
• Southern Dewthread: Florida Panhandle (Gulf Coast)

Same Zone, Different Reality

Both are USDA Zone 8, but zones only reflect minimum winter temperatures. The Gulf Coast has:

• Warmer winters
• Earlier spring warm-up
• Later fall cool-down
• Longer effective growing season

D. filiformis ssp. tracyi evolves to match its local calendar — waking earlier, sleeping later. It's not a defect; it's local adaptation.
