Agassiz Interpretive Trail

characteristics

Considered the dominant grass of Tallgrass Prairie. Name comes from the dusty blue colour of the underside of the blades but this grass could be called "rainbow grass" as its colour is highly variable and it turns scarlet, orange, yellow, purple — just about every colour except blue — in the fall. Maroon coloured seed heads turn brown in the fall. Weathers to a pale copper colour. Thrives during hot summers. May take over areas, displacing other grasses and form virtual mono-cultures.

144,240 seeds/pound; starts from seed, container, or root.
