I don't photograph weeds, but I have bermuda grass types here and they merrily spread across the water surface at the rate of three to six feet a month in Summer
Horrible stuff beside a pond. Yes, I will take a shot of grass spreading on the pond surface, I have roll of film I'd like to get finished. I use kodachrome so it will be at least a week before the slides come back (It's the best archive film available, good for a high res 30 meg file, fine grain film)
Check out the phrase 'bermuda grass' in a search engine and the words invasive, creeping growing habit will be on every page of entries.
here's one reference to bermuda grass, a bit of a giggle....
