Tridens flavus, known as purpletop, purpletop tridens, tall redtop, greasy grass, and grease grass, [1] [2] [3] is a large, robust perennial bunchgrass. The seeds are purple, giving the grass its common name. The seeds are also oily, leading to its other common name, "grease grass". It reproduces by seed and tillers.
In late spring the plant produces rigid flower spikes consisting of three to six spikelets bearing long, stiff awns which assist in seed distribution. When the grass matures, the spikelets fall off in their entirety to germinate on the ground, [ 2 ] and the long awns which give the plant its name assist in dispersal by animals, wind or water.

[2] It is not native to North America, however it has become a serious issue as a weed since it was introduced in the late 19th century. [ 2 ]
The grass is very tolerant of grazing and mowing. [3] A rhizomatous and stoloniferous species, [6] it spreads easily via vegetative reproduction. It also produces seeds, which can be spread in the dung of grazing cattle and remain viable in the soil. [3] Though it does not necessarily require fertilizer, the grass responds well to supplemental ...
