sweet violets- propagating

I was in the garden sunday trying to get a clump of grass from around a tiny patch of sweet violets in my front garden. When I started looking I noticed that there were various other little plants of sweet violets which must have self seeded as i never planted them. They are so tiny (the whole plant is only about an inch high) but lovely. what is the best way to propagate these or shall i just leave them?

 

Depends whether you want them there. If you want to move them somewhere else you could- they seem to be propagating themselves quite happily!
