Many of you already know and love Geranium ‘Rozanne’. Here is cultural information for her and two of her family members ‘Azure Rush’ and ‘Blushing Turtle’.
Geranium ‘Rozanne’
- 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.

Geranium ‘Azure Rush’
- Comes to Rozanne and Friends™ from the Waterers.
- A sport of Geranium ‘Rozanne’ with 2.5″ lighter blue flowers and a more compact, mounding habit.
- Where ‘Rozanne’ rambles ‘Azure Rush’ ambles due to having shorter internodes, which make it neater and lower-growing.
- Vernalization not required for flowering.
- Thrives in hot, sunny locations.
- Like ‘Rozanne’, has a long blooming period from late May until frost.
- Vigorous growing plants have a compact, self-branching habit.
