its extreamly difficult to get names variaty hop seeds as the industry that grows the whole plant does not do seed collecting they just do rhizome cuttings or root cuttings as propigation.
even if you were able to buy seeds you still might have problems with the ratio of male plants, you might have 50 female plants or 50 male plants, you would have to grow all of them to produce one or two females.
where abouts are you, in relation to me in brum.
what i have been considering is starting a hop bank of six variaties and then doing cuttings from them,
i brough three varaiaties off john for a tenner, progress, challenger, target, speak to him and see if he can do some more for you, my next buys are going to be either fuggles, cascade and then may be whitbreads
i can see someone making a small earning from doing small postal cuttings from them
