An interesting hardy geranium with gorgeous chartreuse-tinted new growth and abundant medium purple blooms. If truth be told, this cultivar is much more interesting for its foliage than for its blooms. Bloom color is a dull flat purple, with none of the changing colors or iridescence of other cultivars like 'Rozanne'. This plant is moderately vigorous and has shown reasonable heat tolerance, even as bare root starts during the heat wave of 2012. I am keeping my fingers crossed that it overwinters well.

UPDATE 28 June 2013:
I LOVE this cultivar. Its lackluster flowers last season were probably due to being newly planted and struggling with the heat and severe drought. This year, in their second season and in much cooler conditions, 'Blue Sunrise' is amazing. Gorgeous foliage and a robust yet compact growth habit. As far as I can tell, this is the only chartreuse-leaved cultivar that is reliably hardy in zones 5-6. The flowers are sterile (no seed pods observed, much like equally wonderful 'Rozanne') and have now been in full bloom for 4 good weeks with no signs of stopping. Recent Chicago Botanic Garden trials from 2012 published in Fine Gardening magazine rated this cultivar a solid 3/4 stars, a very good rating. Well deserved!
