Imperata cylindrica |

Imperata cylindrica (cogongrass) is a highly problematic invader of the southern US, from the Carolinas to Texas. It was introduced into Alabama and Mississippi in the early 1900s, but has spread widely in the last two decades. Our work has involved studies to examine the basic biology and ecology of cogongrass and its spread, along with more recent work at habitat modeling and population genetics across the US range of this invasive weed. |
