The Purple eye Purple hull has a much better flavor than the Pink eye which was derived from it and if they have a trellis to climb, they will continue to produce peas until frost. Claud
This picture shows a double row of Pole beans, but if you look to the row on the right in the picture, that is Purple eye Purple hull peas. On the end of the row the peas are growing normally since there is no trellis available, but as soon as the trellis starts, the peas started climbing and took it over. Who knew.
And when I say climb, they grew to the top of the 7' trellis and back down to the ground producing peas all the way along until frost took them out.
