I just bought some hops from Seven Bridges Cooperative, including two American-grown hop varieties I had never heard of before, Ivanhoe and Bravo:

Interestingly, the Bravo hops are grown on an organic farm in Idaho.

California Ivanhoe Organic Whole Hops
8% AAU. 4.6% Beta. The original California Cluster variety has been rejuvenated for the first time in more than a half century. Similar in profile to a Cascade with a moderate alpha in the 8% range, it has a nice aroma with mellow hints of citrus and pine and the strong floral/herbal notes typical of English aroma hops. The exact origins of the Ivanhoe hop are unknown but the original California Cluster hop parent was a cross between English and American varieties. Great for American style ales, California Common, stouts, and IPA's. Try in recipes that call for: Galena, Cluster, Northern Brewer.

2010 Crop. 13.5% Ave. Alpha Acid. This is a new breed of American hops, which are rapidly becoming a favored bittering hop. Ours are organically grown in the state of Idaho. Bravo hops are descended from Zeus and Nugget. They have a very clean and smooth bitterness and highly pleasant aroma. Aromas of light fruit (apple and pear) with a flowery note dominate. Very light hint of tangerine and apricot, and slight earthy background. Exhibiting bittering qualities similar to Chinook, Bravo is a great hop for stouts, IPA's, and other big beers. Because this hop has such a pleasant aroma it is a great candidate for a single hop beer. The quality of these hops is proof beyond a doubt that American hop growers can produce a superior quality hop using certified organic methods.
