I have an old lamp post I grow vines on. This year I want to grow hyancinth beans for their ornamental properties and some runner beans for their yumminess properties. They're going to get all intertwined and I'm worried that once the flowers fall off I won't be able to tell one bean pod from the other when harvesting.
Are the hyacinth bean pods purple when young or do they only turn purple when they're mature?
PS - I know that I can eat the hyacinth beans, but after researching it I've decided I don't want to.
Hyacinth beans are purple and scarlet runners are green (are those the runners you are planning to grow?) Hyacinth bean pods are short and squat, like a lima bean pod. They are also shiny. Runners are much longer and slim. Even Romano types, which are more broad, look nothing like hyacinth. I'm not sure about purple runners but if in doubt don't plant them together.
My Ruby Moon Hyacinth beans turn purple early. But MaypopLaurel is correct - the pods and beans inside never look alike. You will probably figure out which is which - But even if you forget, You can post a picture of your various beans next spring and we can tell you which is which.
And Ladysoth - I agree, Hyacinths are more or less an ornamental. If you really want to eat beans, there are better tasting ones to grow. I grow Hyacinth, Scarlet Runner (Ornamental & edible - I pick them to keep them blooming), and bush beans just to eat.
