I don't know if there's any way to tell them apart accurately at this point, that's 5 different cultivars... The blackjack will normally be the darkest green & Yukon will be the last to go dormant when the weather goes cold. Other than that, it's anybody's guess

Blackjack and Triangle will be the tallest growing ......Triangle contains "Mowhawk' which grows tall and is lighter green than all the others mentioned.

Thanks reelJake and Tom, which cultivar would have the finer blades. I am looking to seed another area and want very dark green and fine blades in seeded form

Blackjack would be a good choice, and its inexpensive too !

If you wanna go super nice (hybrid bermuda look) probably go with 'La Prima xd ' blend , or ' Princess 77' or 'Royal Bengal'

Is laprima fine blade and dark geen
