I would encourage you to read the following article about turf genetics and mutations. If you ever looked at a golf green, Bentgrass or Bermudagrass, and noticed the "patches" of what appears to be different grasses and wondered what causes it, this article explains that nicely. Often times, members at different clubs are disappointed with their brand new greens, consistent and uniform, turn patchy over time. The older the green gets, more variation occurs. I agree it isn't as attractive but it is also important to remember that visual aspects and playability aspects is sometimes a difficult balance. What looks good in the form of healthy turfgrass, doesn't always play well. As a mentor of mine at Augusta National says, "You don't putt on color!"
