You could give Willamette a try (Glacier would be another option - described as a citrusy version of Willamette). Maybe pair it with Cascade.
Willamette
Country of Origin: USA (USDA)
Noble: No
Uses: aroma, moderate bittering
Beer styles: English beer styles; American Pale Ale; American Brown Ale
Substitutions: Fuggle
Alpha Acids: 4 - 6%
Released from the U.S.D.A. hop breeding program in 1976, Willamette is a triploid (some sources say tetraploid) seedling of Fuggle bred to be easier to grow in the United States. It's still less vigorous than most modern hop varieties, but easier to grow in most areas than the very fussy Fuggle.
Willamette has a mild, grassy, floral and slightly spicy aroma similar to Fuggle, and is often used as a substitute, especially in the United States where Fuggle does not grow well. Willamette is extensively planted in the U.S. Pacific Northwest
Glacier
Country of Origin: Washington State, USA
Noble: No
Uses: bittering, aroma
Beer styles: American Pale Ales, IPA, ESB, Porters, Stouts
Substitutions: Willamette, Golding, Magnum
Alpha Acids: 3.3-9.7%
Released in 2000 from Washington State University, supposed to be a balanced bittering/aroma hop. Said to be a more citrusy version of Willamette.
