It a bit expensive the seed I've got alp its barenburg - Medal, it cost me £130 on offer but it is a 20kg bag, I don't think you'll be interested in it. Look on ebay you want a grass seed high in fescue's because one its has a narrow leaf and looks good and most importantly for you is that they are for more drought tolerant that other variety's, chewing fescue or slender fescue are the better fescue grass but unimportant in just a normal lawn.
You know me so well! £130 I paid 79p for a box of 125g, I think and they have now become tuft! OK, I will have a look at ebay. Wonder if seeds in the box of First Cut is admissible in quality! I'm not going to win medal for mine!
