No, not that kind of grass; the grass (-es that comprise the fairways, greens, and rough.)
Have you noticed that with the extreme heat some golf courses are watering like mad even to the point that there is significantly less roll in the fairways? Other courses, although watering during the heat spells, seem to be able to maintain their grasses with less water and therefore have more roll and the grass seems to be thriving.
Welcome to the Sacramento Valley where no grass type is able to grow 12 months out of the year. Some grasses like the hot summer and some like the cool, wet winter, but few grasses likes both. A few newly developed hybrids do pretty well, but their cost for a golf course is prohibitive. You might be able to afford enough of this hybrid seed to plant the lawn of your patio home.
Golf courses that have the money or that have been constructed more recently (in the last 20 or so years) generally plant the fairways and green surrounds with one type of grass. The two most popular grasses for golf in the Sacramento Valley (because a golf balls sits on top of the grass when it is cut short) are bermuda and rye. Older courses and those without luxurious budgets tend to have a mixture of grasses including bermuda, rye, and other local grasses.
Grasses fall into two general categories, warm season grasses and cool season grasses. Bermuda is a warm season grass; it does well in the heat and goes dormant in the winter. Rye is a cool season grass; it does well in the cool weather and struggles to survive the valley heat. When you see cart restrictions, lots of water running, and bare spots during our hottest summer days, that course is likely to be planted in rye grass.
Personally, I prefer bermuda grass because the ball sits so well on it and I don’t play in the winter. (Mary is the President of the “Play It Warm, Dry, and Forward” fan club.) While rye grass is green and offering its best lies in the winter months, Bermuda is “USGA golden” brown when it is dormant which draws complaints from those who live on a course planted in that grass. The dormant grass does offer playable lies for those of you who insist on playing in crappy weather.
The type of grass that is planted in the fairways will also dominate the rough. Warm season grasses make it more difficult to hit a ball out of the rough than cool season grasses of the same length. If you are playing on a course with bermuda as the dominant grass, be aware that your lies in the rough may not look deep, but they are extremely difficult.
One final note: If you need to sleep, try a Kush. If you like a “busy” grass, you will want a green style. If you are playing golf, neither works.
