Can anyone please tell me what type of weed this is? It is growing spread throughout an area of grass/lawn, in mid-spring in Toowoomba, Australia.
What would be an effective method to control it?
Slender vervain, Verbena rigidia http://bie.ala.org.au/species/VERBENA+RIGIDA#
https://www.moretonbay.qld.gov.au/uploadedFiles/moretonbay/environment/vegetation/purple-top.pdf has some control methods. I've never had this as a weed. I ID'd it on it's similarity to verbenas I know and went from there...
