Borage
Borage can be identified by its bright blue flowers, which are edible. The leaves, too, can be eaten, and this plant can either be enjoyed raw, or boiled and used as an alternative to kale. This is another plant with a cucumbery taste, and its high levels of minerals such as manganese, copper, zinc, and magnesium mean that it is often used as an herbal remedy to treat a variety of illnesses.
