This Oxalis spread over all gardens and areas here the last few years and
destroys lawns and it is almost impossible to get rid of.

Interesting. If you mean that little one with yellow flowers (I always forget
the species name), it is a pest here too, but we have worse ones in the lawn.
Queen Anne's lace isn't really a noxious weed in gardens here. It is very
common on roadsides & other waste places.
