Arboretum exhibit shows benefits of turfgrass
Oregon grass seed farmers can feel right at home in Washington, D.C., this summer with the National Arboretum highlighting turfgrasses in a display titled The Grass Roots Exhibit.
Oregon growers, in fact, have a stake in the exhibit: The Oregon Seed Council donated $50,000 to help construct and maintain it.
Coming at a time when home lawns are under fire in California and other states, Roger Beyer, executive director of the council, said the council felt it was important to show the positive side of grass.
“We felt it was important that our story be told,” he said.
In the exhibit, signage identifies which grass species are planted in the different sections and provides glimpses into some of their environmental, aesthetic and recreational benefits. Signage also directs visitors to a website where they can obtain more information on the displays.
Now nearing one year old, the exhibit has been a popular draw among arboretum visitors, said Geoff Rinehart, the exhibit’s coordinator and a former turfgrass research technician at Washington State University.
Among the exhibit’s more popular elements, one displays an artificial grass sports field next to a sports field of Bermuda grass. “There is a lot of appeal there to compare and contrast when they are side by side,” Rinehart said. “People are pretty engaged with that.
“And of course everybody likes the golf exhibit,” he said. The golf exhibit includes bentgrass grown from seed produced in Oregon. “A lot of folks who have never been on a golf course are able to get an idea of what a golf putting green feels like.”
The exhibit also features a display of perennial ryegrass grown for seed. “We’ve let it grow to where we have the seed heads and we’ve got a sign out there that talks about the importance of growing grass for seed for turfgrass,” Rinehart said.
“The grass plants aren’t as big as they would be in the Willamette Valley,” Rinehart said. “But we have signage that says, ‘This is what a grass plant looks like when it is grown for grass seed.’
“We also have perennial ryegrass in our cool season lawn display, which we keep at typical lawn-grass height,” he said.
Other grass species displayed include tall fescue, fine fescue and Kentucky bluegrass.
The exhibit also provides glimpses into agronomic benefits of grass plants in a display highlighting the use of cereal rye, wheat, oats and barley as cover crops.
“Our message is these crops are grasses, too, which is news to most people,” Rinehart said. “Especially in D.C., many people have never seen a wheat crop.”
The exhibit, located in an 8,000-square-foot field adjacent to the arboretum’s main entrance, is scheduled to run through 2017.
