The tallest of the cranesbills in our garden, growing to a large, billowing mound, with lots of black-eyed purple flowers late spring into summer. It happily accepts its position in full sun and occasional drought, which has earned our original plant and several of its offspring prominent positions in our front lane.
||ordinary garden soil
||Self-seeds sporadically in our garden. Not easy to germinate - probably requires a lengthy cold stage.

|jennifer||Jun 24, 2010||Wow this is an awesome page. I've had Wargrave pink for years and always just called it the "pink one" until today when I found your site. A friend gave me what appears to be a psilostemon that i was able to identify by the great leaf photos! next I will identify my purple one! Thank you so much!|
|Margaret||May 20, 2016||Hi - we did love these plants, we have Geranium Psilostemon, which unfortunately is taking over our small south facing garden in Scotland. Tried pulling and digging it out but it persists.
Any advice to control this?|
That really surprises me – G. psilostemon doesn't spread by running roots, and has been a polite reseeder for me, quite easy to pull up where it isn't desired. I guess it really likes your garden!

I added my best estimate of hardiness zones to the profile. You can find more sites that have this kind of information using the plantlinks link on this page. As you'll see, different sources don't always agree on hardiness.

Cold germination appears to be the way to go.
