The Asian legume group includes fruits (usually known as pods), which are eaten at the immature stage with edible immature seeds (green shell), and some young leaves and stem tips. For instance, the winged bean has edible leaves and roots, though the latter are rarely cultivated commercially in the continental United States. Pole bean, long (or yard long) bean (both dark- and light-green colors), broad bean, and lablab beans are commercially grown in south Florida. All the pole or indeterminate types can be grown on raised beds with or without plastic mulch using drip, overhead, or subsurface irrigation. Fenugreek does not grow well in rocky soils, such as those found in Miami-Dade County. Pigeon peas are a semiperennial shrub in warmer areas. Many pigeon pea and winged bean varieties are short day and only flower during the fall. There are some day-neutral varieties available for both crops. Edamame varieties, especially those from seed companies in the United States, are sensitive to daytime length, so care must be taken to select varieties for one’s growing area. Japanese varieties are classified as “summer” or “fall” types, indicating when they flower. Fertilizer recommendations for pole, long, or broad beans are generally applicable to this group. All of these crops are started from seed, though winged beans require scarification prior to planting. All the indeterminate types need some kind of support, ranging from individual bamboo stakes to trellises. However, some bush-type broad beans (Indian type) do not need trellises. For pest control products, these crops are included in the legume crop chapter.
