Grown for its chartreuse/yellow new foliage, its magenta flowers (NOT violet/lavender) with a black center, its long season of bloom, and its rambling, weaving habit. Looks a lot like 'Ann Folkard', but it's said to be more heat tolerant, and performs better than 'Ann Folkard' in eastern North America. Easy to control, because the stems do not self-layer.

In 2005, the Royal Horticultural Society granted this cultivar its coveted Award of Garden Merit. [HYPERLINK@www.rhs.org.uk]

In the Chicago Botanic Garden's hardy geranium plant evaluations (Z5b), this cultivar survived only two winters. [HYPERLINK@www.chicagobotanic.org]

Bred by Alan Bremner, it's a hybrid between G. psilostemon and G. procurrens.

As long as you grow 'Anne Thompson' where she can stretch out, and hug her neighbors....she will be happy, and so will you! Mine has sprawled...er, I mean stretched out to more than 4 ft in all directions!! But finding her cute little blooms here, there, and everywhere is OK by me....I like them surprising me....
