Hi. I have been saving seeds from my broad beans for five years now; red seeded, originally from Koanga Gardens. This year for the first time a number of the beans are normal green - there is no intermediate shading, they are all either red or green. I guess this means red is recessive? Anyway, I like the look of the red and choose the deepest red seeds to plant - so how can I keep the colour going?
Neither of my neighbours have gardens, though I don't know about further away. . . so is this likely to be cross pollination or just random luck?
