Long story short.... I tried out Millennium tall fescue last year. It is put out by Turf Merchants. Great stuff! COme time to overseed this year I settled on using the Turf Gem II blend that contains Millennium, Focus and Aztec II. When I stopped by my supplier and pointed out what I wanted on my price sheet, I saw 2 listing for the Turf Gem II and of course I asked for the new one with the Millennium. Well when I finish up seeding I always cut the tag off the bag and file it so I can reference what's been planted at each account. After finishing the last account, as I was cutting off the tag I looked and realized I just got through overseeding a Millenium lawn with a bag of the other Turf Gem II. This was the only bag out of the bunch that was the other stuff. It contains Adventure II, Anthem II and Aztec II. Did I just make a big mess and combine 3 varieties that blend together and one that doesn't? I'm sort of comforted by the fact that the Aztec II was in the other blend with the Millennium. But I can't really be sure the Aztec II hasn't changed you know? These 4th generation turf type tall fescues like Millennium and Focus have a really dark green genetic color compaired to others. I hope it doesn't turn out 2 different shades and look like crap. If you are familiar with these varieties please reply.
