Perennial Geraniums

I found out today the reason why the hardy geranium is called the cranesbill. Apparently the when the seed head ripens and explodes it resembles the open beak of the crane's bill. 

I hope this isn't Johnson's Blue geranium.  I do like the colour and the size right now is perfect, so I hope it stays small and doesn't sprawl like Johnson's Blue, or it will have to be moved.

My favourite geranium - sanguenium

My favourite geranium is sanguineum. It is low bushy, and the leaves turn bronze in autumn. But best of all it blooms almost all summer with magenta flowers. It benefits from a good clipping after the first flush of bloom to make it compact again and to reset bloom.  I received it from my Mother-in-law, who got it from Victoria, B.C.'s Butchart Gardens!  Now that's history!

One grows this geranium for the colour of the leaves.  The flowers are pale lavendar and don't bloom for long.

I have Hocus Pocus. It has dark purple leaves and pale lavender flowers. But you grow it for the foliage. It is not easy to grow well and once it likes a spot, I don't suggest you move it.  I had to move one out of necessity and happily it likes the new location better. It's in more shade, but the plant isn't as straggly any more.

What is it? I hope someone out there knows.

What is this plant?  It is a self seeding annul and is low growing .  I don't know how it arrived in my garden.  I like it, but ...
