Gardeners' Notes:

Neutral coriaceous On Oct 22, 2014, coriaceous from ROSLINDALE, MA wrote:

From a distance, the flowers appear pale gray-blue. The petals are blue-violet, with their network of fine veins delicately emphasized in white. Up close, they are as intricately patterned as butterfly wings.

In an article on the RHS website, Graham Rice names this one of the 10 best hardy geraniums for the garden.

The Royal Horticultural Society has granted this cultivar its coveted Award of Garden Merit (AGM).

At the Chicago Botanic Garden's hardy geranium evaluation, it bloomed from late May to early July and earned a performance rating of "good". Clumps reached 24" tall and 38" wide. Cutting back after flowering improved habit and health.

Positive Gabrielle On Jan 26, 2006, Gabrielle from (Zone 5a) wrote:

I like the flowers on 'Mrs. Kendall Clarke' (also 'Mrs. Kendall Clark'), but the plant does have a tendency to flop out of its bounds. It also self-seeds a little. Stratification aids germination of seeds.

Blooms late May to mid July in my garden.
