A spring ephemeral from southern Europe and Asia Minor---it goes dormant after its spring flowering.

I bought some tubers and planted them in the fall. Some flowered the following spring. The following spring, only a few returned. The next year all were gone. This was in a bed in partial shade with silty soil that was not heavily irrigated.

The flowers are attractive, and I've been meaning to try it again in another location.

Easily and inexpensively available from sellers of fall bulbs.

I found this Geranium a bit difficult to get established. I have about 30 different Hardy Geraniums and this is the only one that will not clump up, nor fill out well....I have tried it several times.....but probably won't try again. Pretty blooms when it did bloom for me.....
