The beauty of weeds!

Weeds are just flowers by another name. Montbretia and Vinca are "Flowers" but they are weeds here. I'd rather have more dandelions and clover than montbretia & Vinca.
I know you'll disagree but grass is a weed in my opinion. I'd prefer to have a "lawn" of wild flowers and weeds than grass. You don't see many butterflies and bees on grass, it doesn't feed the birds or people. Its just pointless!

As an ex sports groundsman I am hardly likely to denigrate grass, which I spent half my life learning about (my children know all the latin names of the various cultivars as they helped me to rehearse  them parrot fashion prior to exams) and cultivating to a high level for football,rugby,cricket,lacrosse,Gaelic football,American football,hockey and a host of other sports including, if you can believe it,Quiddich!

I also think that visually a well kept lawn sets off a not so well kept border,likewise with an uncut area of grass alongside a cut area?

The only time I wouldn't have a lawn is if the garden was too small for it.

Horses for courses though,I can see your point veggie, but surely its better than a paved area ecologically?
