The parsnip we know today evolved from the wild parsnip which is still growing in Europe and Asia. It was a staple in the middle ages, but fell into disuse with the rising popularity of the potato. It is naturalised in New Zealand.
One of the most ancient old-world vegetables, the garden pea can be traced to the Bronze Age. It was domesticated in Europe and later in southern Russia, Armenia, northern India, Pakistan and the mountains of Ethiopia. Primitive peas were found in the city of Troy. This vegetable reached China early in the Tang Dynasty, 600 to 900 BCE.
The ‘common bean’ Phaseolus vulgaris – phaseolus being Greek for bean and vulgaris Greek for common – covers both green beans (French beans) and dried beans such as pinto, navy, kidney and borlotti.
Basil flowers are coloured white through to purple. They have an abundant and pungent nectar, and rely on insect pollination, so one basil will cross with others. You will need to separate different varieties by as much garden space as possible (preferably fifty metres).
Onion is a hardy biennial from the southern parts of Russia and Iran. It was disseminated by the Indo-European hordes in their numerous migrations.
Very ancient forms of onions are still for sale in Middle Eastern markets. Onions were considered sacred and were eaten in copious quantities by the Egyptians who honoured them in some of their monuments.
There are at least two main types of fennel. There is a huge difference between the pungent, roadside weedy fennel and the much-loved, sweet garden Florence fennel, which is also called Finocchio, and has large, swollen stem bases.
