Is Clover Invasive?
I've read a recent article about Durana white clover, and it sounds like it could spread a lot when planted for wildlife feed plots. I'm wondering if it is safe to plant in west central Missouri (specifically Johnson County). The developers claim a grazing survival trial of only 4 years. I'm not so concerned with the grazing as to the spread, possibly choking out everything else.
All white clovers produce lots of seed. Some of that seed is hard seed—more hard seed than many other types of clover. Because of that hard seed, a lot of white clover stands come back, after seemingly being long gone, when weather conditions are more favorable. Durana probably has this characteristic too. Although it is a clover developed in the mid-south and southeast U.S., it will probably do fairly well in west central Missouri. See Georgia data at http://www.caes.uga.edu/applications/publications/files/pdf/B%201251_3.PDF.
You might get a little winterkill in your area, but I think the hard seed will allow white clover to come back with most spring weather. Drought can be a problem too. But, again, the clover should come back with the rain.
The bottom line is, I really doubt that you will have any issues with this clover being too aggressive. See this Missouri document on white clovers: http://extension.missouri.edu/p/G4639.
