Just east of Beaumont, in the small town of China, they say the grass grows greener, green enough to be used in golf courses throughout the state.

On Mike Doguet's farm is where some of the zoysia grass started its journey from Texas to Rio.

"It's nearly half as much herbicide, insecticide, and also fertilizer that Bermuda grass takes," Doguet said.

Doguet tells us the grass is easier to grow and maintain, and made it more attractive for the Olympics golf course in Rio.

Doguet told us that him and his brother, David, presented a patch of their grass to a farmer in Brazil five years ago. That's where those farmers grew the greens you'll see when Olympic golf starts on Thursday.

"About 88 percent of the course down there is zeon zoysia, it's tee boxes, fairways and green surrounds," Doguet explained it's more durable than the Bermuda or St. Augustine grass normally used on golf courses.

"But it [zoysia grass] the minute they get water on them they green back up, where St. Augustine, if it goes brown, it's dead. So that's the difference in the grasses and that's why it was picked for that particular course," Doguet said.

The grass received a lot of attention, including from Tiger Woods who picked the zoysia grass for his first American golf course, Bluejack National in Montgomery, Texas.

Doguet thinks the zoysia grass will take over golf courses all around the world.

Mike's brother, David is currently in Rio watching the Olympics. The golf course will be on display when the men's tournament starts on Thursday.
