I received this plant from a friend in the Spring. I wasn't expecting much from it during it's first summer, but it completely surprised me. It mounded beautifully and the delicate flowers look perfect in my planter. I would highly recommend it.

This cultivar has been growing wild in my front yard since I bought my property 8 years ago. I love it and have done nothing to limit it's spread. It's pretty much stayed under control. It does reseed, though minimally, and has retained it's variation. Gets kind of scraggly by mid to late summer but I just mow it down then, and within a couple of weeks or so it's folliage is looking great again. Will even reflower within a couple more weeks until the first really hard frost. I collected some seeds this fall and will WS or direct sow in spring somewhere else on my property to see how it does. Not sure of the notes under Seed Collecting as it doesn't seem to apply to the hardy geranium I have. Will post a pic.

I have found this cultivar to be an excellent garden plant, especially in very hot, bone dry summers. It withstands every temperature extreme here in Zone 5a/b, where summers can attain 100 degrees+, and winters can see the mercury falling to -22F. Of the hardy geraniums this one is my first choice for all around performance. It blooms well into late summer and I find it re-seeds with no apparent loss of plant characteristics.
