Kentucky blue grass is blue-- the way a blue spruce is blue, or the way some Hosta's are blue-- which is to say is a shade of green with a definite bluish cast– it is America's native bamboo– somehow, bamboo is different than other grasses-- but the details of the difference are lost. Any one with more knowledge of botany?

I have the habit of reading– and unlike those of you who have gone to university and actually learned one or two subjects extreme well, and many subjects very well, I am more of jack of all trades. I read a bit of this and a bit of that, and know a little, and then forget half of it, about all sorts of things.. like blue grass being a bamboo and not just a grass and then forgetting how bamboo differs from grass.
