Geranium_Rozanne_cu_300x300    Geranium_Rozanne_fp_300x300    Geranium-Rozanne-1

  • Comes from Donald and Rozanne Waterer, UK.
  • The best, most garden-worthy hardy Geranium you can grow!
  • Large 2.5″ (6cm) saucer-shaped, violet-blue* blooms with white centers flower profusely from late spring through November, or until frost—they just never quit!
  • *Her color can appear more violet under high light and temperature (as pictured far right), but more blue under shaded, cooler conditions.
  • Vernalization not required for flowering.
  • Unlike many Geraniums, ‘Rozanne’ has great heat tolerance, too!
  • Slightly marbled with chartreuse, deep-green foliage.
  • Plants form nice mounded clumps but her branches have a tendency to ramble, which makes a good groundcover, and allows use in hanging baskets or for “spillover” plants in containers.

  • Thrives in hot, sunny locations.
  • Like ‘Rozanne’, has a long blooming period from late May until frost.
