I just did an extensive search. There are very few Hop Rhizomes out there still and no nugget. Sorry.
http://www.freshops.com/ is still selling a few diffrent types. I put a few in the ground at the start of the month. I know I'm late, and though we have a longer warm climate, I'm looking to get them off and running mainly for next year. We'll see! I bought on a Friday and they were at my door on Monday.
I planted the 3 magnum rhizomes on Friday 4-15-2011 and 2 already have bines! !!!
The first one sprouted yesterday, has 3 bines and the next sprouted today, has 3 bines, so the third should be tomorrow with 3 bines.
I ordered this years rhizomes from http://www.freshops.com/ they were waaayyyy healthier than the place I got my rhizomes from last year (I won't mention their name). Huge, thick lots of shoots or buds whatever you want to call them. So far with my 2 rhizome orders from 2 different places I recomend Fresh Hops.
