Gardeners' Notes:

Neutral coriaceous On Oct 20, 2014, coriaceous from ROSLINDALE, MA wrote:

Vigorous, prostrate, long-blooming. In 2005, the Royal Horticultural Society granted this hardy geranium its coveted Award of Garden Merit. An article on the RHS website recommends this as one of the ten best hardy geraniums.

At the Chicago Botanic Gardens 2004 hardy geranium evaluations, it bloomed for about 7 weeks and reached 4' across. It earned 3.5-4 stars out of a possible 5. []

Rebloom is better in cool-summer climates. It is said to tolerate poor drainage better than most geraniums.

Geranium sanguineum x G. procurrens. The leaves look like G. sanguineum and the flowers and habit are more like G. procurrens. The stems weave and climb but unlike G. procurrens they do not root.

Introduced by Axletree Nursery, Starvecrow Lane, Peasmarsh, Rye, East Sussex.
