Hi to
SF bay area folk,
There are still some growing Tropaeolum tuberosum for sale
up at the UC Botanical garden.  They do better with a little
warmer climate than Berkeley but will grow here.  The tubers
are quite tasty.  They are among the Lost Crops of the Incas
Little-Known Plants of the Andes with
Promise for Worldwide Cultivation.  BTW that book is
available online.
