Dear Pat:
If you go to bestapples.com (which is the website of the Washington Apple Commission), and, under Apple Info, choose 'apple varieties', you will see photos of nine apple varieties grown there.
Our local paper showed a photo from the 1910 Watsonville Apple Show. There, 12 growers from our small county in the Sierra Nevada foothills (Tuolumne County, California), displayed 52 varieties of apples!
A few independent growers here are preserving some of those heirloom varieties, but, alas, most are gone.
Best wishes,
Petra
