Hedge garlic. This native biennial plant can be found wild in many hedgerows so there is probably little need to cultivate it. The leaves, flowers and young seedpods have a flavour that is somewhat like a cross between garlic and mustard-fairly pleasant when added in small quanities to a salad. This is one of the more shade-tolerant plant on the list. If you decide to culitvate it then collect the seeds from wild plants in early summer and sow them straight away in situ. They will normally maintain themselves by self-sowing. (Fern, K., Fern, A., & Plants for a future. (2013). Edible Plants)
