I 3rd Cascade hops. They are disease resistant, grow like gangbusters, heavy hop cone producers and add excellent flavor to any beer or ale. Plenty of time to get them in the ground.
I planted mid April last year and harvested 1.8 pounds from my Cascade bines (1 rhizome, one rope, 3 bines)
I added a couple new sources to my list of online hop rhizome sellers
