Like See Hes, I grow long beans and winged beans. Even here in Brazil in zone 9b, in a distinctly hotter than usual summer, they take FOREVER to get started. A long time to germinate, a long time to get growing.... and long beans are slow too, but the winged beans are something else.
I plant normal string/pole beans, long beans and winged beans together. The string beans are done by the time the long beans start producing (victims to aphids and also just pooped out). The winged beans don't really even start producing at all until the long beans are about half done. And all this assumes no pest attacks, drought or anything else. The leafcutter ants like the winged bean leaves, and need to be monitored. This is the first year I'm actually getting a decent harvest of winged beans, having started quite early and given them plenty of time, plus hotter than usual temps.
