oxalis (probably the pink flowered one)
Id definitely try to get rid of the alkanet unless you have a 'wilderness style'garden.
Id try to get rid of the oxalis too. you won't succeed with either but try to control them.
I like the euphorbia but not everyone does. If you decide to get rid of it don't get the white sap on your skin as it can cause burns when exposed to sunlight b
