Summer Flowers 2026 in the Bay Area: What’s in Season, Every Occasion, and Your Complete Warm-Weather Guide

Summer in the Bay Area is complicated — it is 95°F in the East Bay and 62°F with fog in San Francisco on the same afternoon. Your flowers need to work for both. Here is the complete guide.

🌻 What’s in Season: June–August

  • June: Peonies (early, last chance), roses (peak begins), sunflowers, dahlias (early varieties), protea, stock, delphinium
  • July: Roses (full peak), sunflowers, dahlias (main season), zinnias, gladiolus, hydrangeas, lilies, lavender, California poppies
  • August: Dahlias (peak), sunflowers, zinnias, rudbeckia, celosia, late-season roses, asters, king protea

California-grown summer flowers are exceptional. Many stems come from coastal and Central Valley growers who supply the San Francisco Flower Mart.
