They can both spread if they're happy, but it's easy to pull up the roots if they wander too far. Very nice for shady areas, ground cover, under trees, or in a rock garden, and easy to care for. These don't bloom as long or as continuously as other cranesbills, for me. This is still an excellent perennial because the foliage is very attractive and fragrant even when not in bloom. I am in zone 4 and have been growing these for about 10 years.
Purchased two 'Karmina' plants locally "firesale" in the Fall.

Just as well, as I would probably have skipped 'Karmina' if I had known it was rated for zone 5. 'Karmina' made it through the winter without noticeable injury in a relatively unprotected area, formed a nice mound and a good number of flowers, although not as many as 'Biokovo'( Geranium x cantabrigiense 'Biokovo'). Bloom time was fairly long, but the number of blossoms trails off over time. Planted 'Karmina' next to 'Biokovo' and they look nice together. Same flowering time, same flower shape, similar leaf shape and similar mounding habit. The flower of 'Karmina' is pinkish-purple and 'Biokovo' is mostly white. 'Karmina' is a bit smaller plant (perhaps just less established) than 'Biokovo' and could be "swallowed up" by nearby plants. I recently trimmed off the spent blooms, so I do not know if there will be a second bloom.

Has been quite the vigorous grower here in zone 5! Very hardy and requires minimal care.
zone 4a hardy too - a pinker form of Biokovo - seem to be a bit less vigorous than Biokovo. I have a few patches of this variety.
The foliage is fragrnt. The plants I bought were labeled Zone 4 hardy.
Mine are growing in nice and full, covered with flowers. They are wonderful in combination with catmint - very complementary colors!
