Yardlong Beans (5 of 8)

Also commonly known as asparagus bean and snake bean, the pods will grow up to 30" long; they grow especially well in hot, humid climates because they're native to tropical Africa. They're also an important food crop in Southeast Asia and in the U.S. can often be found in Asian markets, where they are labeled Sitao, Changjiang dou or Cheung kung tau.
