Probably the worst weed of the world 
Does there exist a country near the sea without this weed ??

Oxalis pes-caprae? Is it?  There are nice multi-petalled forms.

[bulborum]

and lots less invasive
I grow two collections from Corsica and Sicily
I know also a place at the Algarve where they grow
that collection died 
they are fantastic and you can't compare them with the weedy ones

I've never seen the Oxalis pes-caprae in Belgium or the Netherlands. What I read about it, it's not hardy there.  I can see here in Spain, that it is very invasive. But the leaves and flowers are nice, so if I can find seeds I'm going to try it as an annual. Since it's not hardy in my zone 6, I don't think it will get invasive in Belgium.

Thank you Hans for the identification of 4 of the plants I found.

I think this is Centranthus ruber. Am I right?
