OK, I get it. Isn't that more aptly described as grass colors? Different ground texture, to me, sounds like differing firmness or porousness or a different feel to the actual dirt. I wasn't quite understanding how that would necessarily be a good thing. Most poa greens have multiple colors in them - and it looks lousy. I also understand that different grass types have different feels and playing characteristics. But to me, I'm not quite understanding this, still. I was there. It seemed to me that the greens and the fairways and the rough were all different colors, ie, ground textures (by your definition). Is that not enough? And wouldn't this same criticism apply to pretty much every course except those lucky enough to be in the sand hills or the Oregon coast?
Dave, I'm not speaking for Bradley, I'm just relaying what I understand the term texture to mean.
Looking down at the grass is not what I would call texture. The blotchy look of Poa, might not appeal to people's aesthetic, but it rarely, if ever, affects play. As an FYI, it's becoming common to plant multiple strains of grass (i.e. fescues) to see what type, each specific micro climate will suit best. The strong will take over the weak, and as I understand it, that's the goal.
Textures work best when looking out on the long views. My suspicion is that it acts like undulations, in it's ability to trick the mind. Making judgement more of a challenge. Cutting the same grass type at differing lengths, creates a tiny bit of different color contrast, but on a spectrum, they are very close. Starker contrast towards browns and reds are more natural looking and NOT just in the sand hills.
While I've never been, I've seen countless photos of heathland courses where this contrast is positively delicious. Examples in every region I'm sure are available.
