They’re not like other beans at all. They get bigger before they start to flower, and once the flowers are done and the bean pods come on, they take longer to fill out with beans.
And they’re purple on the ends! And they’re worth waiting on cos they’re good! They stick straight out until they get heavy with beans inside, rather than hanging down from the start like other types of beans.
Beware that wasps and yellow jackets are on and around the pods once they form. Nectaries at the base of the pods secret a nectar even after the flowers are gone. They don’t sting or damage the pods, but they might sting the gardener!
It’s a very interesting plant to grow, and they’re so good fresh.
