William Woys Weaver

The Roughwood Seed Collection, which now comprises about 4000 varieties of heirloom food plants, was begun informally in 1932 by my grandfather H. Ralph Weaver (1896-1956).

I discovered his seed collection at the bottom of a freezer many years later and decided to take on the responsibility of growing out the rare and unusual plants he had accumulated. Since then, I have added thousands of new plants to the collection (and given it the name Roughwood, after my 1805 house in Devon, Pennsylvania) .
