FedCo's catalog is also really... interesting. I always be sure to order something from them every year to ensure I continue to get a catalog. When it arrives (usually in the dead of winter) it is good for some cold, dark evening by the fireside reading. http://www.fedcoseeds.com/forms/sds36_cat_highres.pdf An example: 2512LY Olympia (38 days) F-1 hybrid. No more bad political jokes—our Senator Olympia could no longer stand the dysfunctional Congress and finally retired. For an almost fully functional spinach, consider her namesake that always stands as strong in November as Olympia did at the ballot box. An outstanding performer for the fall crop and even early winter but not as hardy as #2558 Winter Bloomsdale, Olympia grows fast, producing enormous yields of mostly smooth leaves up to 5x6" almost entirely lacking in oxalic acid taste, so her mild flavor goes down easily. But Olympia can’t stand the heat, and bolts quickly when planted in spring.
