Why grow Celosia in Belleair Bluffs?
Belleair Bluffs sits in USDA zone 10a (heat zone 8) with a Cfa (humid subtropical) climate (Köppen-Geiger / VU Wien) — Subtropical Southeast. Summer highs reach 89°F (NOAA NCEI) and winter lows fall to 54°F, at 52ft elevation (USGS). Celosia prefers USDA zones 2–12, killed below 50°F.
