06/11/2013 in invasive plants
I was talking to a fellow garden blogger today… and he mentioned that a part of getting his nursery certified was getting his cogongrass eradicated.
Cogongrass has been in the news, I see reports on “The Farm Monitor” and “The Ag Journal” on network television… I’d seen the field guide to cogongrass identification but I really didn’t know all that much about it… Went to google…
http://www.cogongrass.org/georgia/ made for interesting reading and viewing… in watching those videos, I remarked on it’s similarity to Johnson grass…
cogongrass seems to be worse…
Cogongrass has been called one of the world’s ten worst weeds… This seems like a pretty serious claim, and I was curious what other weeds made the list…
Found a list for Mississippi: http://msucares.com/pubs/misc/m1194.pdf
It’s kind of hard to take it seriously though… a list that includes lamb’s quarter and purslane? Lambsquarter is a valuable food item at my house, and purslane could be… and neither is any great shakes as weeds… If you wanted to include annual weeds, chamberbitter (Phyllanthus niruri) and mulberry weed (Fatoua villosa) would make far better candidates…
It seems like a list of the worst weeds should take into account things like rizomes, stolons, and the born pregnant qualities of the 2 above annuals.
A better list would be this list of Georgia invasives
Glad you asked…
In no particular order,
- bermuda grass
- Florida betony
- johnson grass
- mulberry weed
- Chinese wisteria
- morning glories
- better place cogon grass on the list.
- Stilt grass (Microstegium vimineum)
- wavy leaf basket grass (Oplismenus hirtellus ssp. undulatifolius)
- Japanese honeysuckle
- creeping charlie
- dollar weed (Hydrocotyle sp.)
- Houttuynia cordata
With a bit of walking around other people’s gardens, I could easily extend this list to a hundred… bringing it down to 10 probably wouldn’t be as easy.
Do you have a bad weed? I’d like to hear about it.
