Yarrow
Yarrow Crescent in North Beckton is the only instance of this herb on London’s street signs.
Yarrow
The entire yarrow plant is edible and nutritious, but the foliage is pungent; while both its leaves and flowers are bitter and astringent. The leaves can be eaten young; raw, they can be added to salad. The leaves – with an aniseed-grass flavour – can be brewed as tea.
