Interesting! I too love to grow beans. I usually grow three colors, green, purple and yellow. Yellows are my favorite. But I grew up with bush beans and pole beans just seem strange to me. But I am trying to change and bought a few different varieties of pole beans this year to try.
And I'm very interested in the favas. I tried to grow them in the spring last year and didn't have any luck. Very few even germinated. I have more I was going to try this spring, but a bit earlier than before. Now, since we are having such a cold winter, I'm guessing I couldn't get away with planting them now but maybe as early as Feb. since that's when most around here put in peas and potatoes?
We are also trying a lot of the dried beans and lentils. And cowpeas. And soybeans for eating green.
It should be an interesting year, if I can stay ahead of the Mexican bean beetle!
