look up chiltern or chilturn seeds they have loads of different seeds and if not they mite know someonewho can help .

You need to grow a meadow/prairie to suit your envronment, there is lots written on this subject. I found an American book that might be of interest? The American Meadow Garden: Creating a Natural Alternative to the Traditional Lawn by John Greenlee and Saxon Holt. Also the University of Minnesota have worked on Establishing and Maintaining a Prairie Garden in 1997. Before anyone says so! I know Argentina is not in the USA lol. But parts of the climate can be similar?

Thank you guys. Books are always of interest so that is already a welcome tip. I will check chiltern and chilturn seeds. I found some web sites like http://www.americanmeadows.com and http://www.cheapseeds.com , they sell seeds by the pound and they offer different types of wildflower mix including some based in geographical location but I was looking for a consumer first hand opinion. Thanks for your time
