I would assume it would depend on where you are. We are currently rehabbing our pasture. We planted a mix of rye and winter wheat last fall. The rye is starting to go dormant now, due to the heat. We are keeping our pasture mowed and fertilized to encourage the native grasses that were already there, but shaded out by trees and brush. There is also some bermuda grass back there, and we planted some bermuda grass seed in a few areas.
Our pasture will never be "lush," as we have a sandy clay soil and a hot dry climate. However, with careful managment, we will have plenty of good, nutritious pasture.
The grasses that are in our pasture are indian grass, big and little bluestem, crabgrass, bermuda grass, there is some arrowleaf and crimson clover, and yellow hop clover, and some gramma grass and the like as well. The horses also seem to like the cheat that is growing back there. There is also a LOT of weeds, but they are slowly being choked out as the mowing benefits the growth habit of grasses and allows the grass to choke out the weeds. (Meaning a lot less work de-weeding the pasture for us, even if it takes a bit longer.)
