Imperial Green Windsor is a green seeded variety, noted for good flavour. Long pods, 5-8 green beans per pod.
Prefers a fairly heavy loam but succeeds in a sunny position in most soils that are well-drained. Grows well in heavy clay soils. Dislikes dry conditions according to some report, whilst another says that it is drought tolerant once established. Prefers a pH in the range 5.5 to 7.
Broad beans are often cultivated for their edible seed and sometimes also as a green manure crop.
Grows well with carrots, cauliflowers, beet, cucumber, cabbages, leeks, celeriac, corn and potatoes, but is inhibited by onions, garlic and shallots.
This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby. When removing plant remains at the end of the growing season, it is best to only remove the aerial parts of the plant, leaving the roots in the ground to decay and release their nitrogen.
Young leaves can be eaten cooked. They are very nutritious and can be used like spinach.
Broad bean seeds are very nutritious and are frequently used as items of food. There are, however, some potential problems to their use if they are consumed in large quantities, which can cause the disease 'Favism' in susceptible people.
The immature seeds can be eaten raw when they are small and tender, as they grow older they can be cooked as a vegetable.
