Few flowered leek with wild garlic
At the moment few flowered leek (Allium Paradoxum) is carpeting vast areas of woodland and banks of streams and rivers. Some mistakenly think that the little white flowers that smell of garlic are actual wild garlic or Ramsons flowers but they are very different.  There are only a few flowers on each stalk whereas the wild garlic has many flowers with broader leaves.   Unfortunately the wild garlic flowers are not yet out but I managed to find a few growing in a sheltered sunny spot.
The flower heads of the few flowered leek produce many tiny bulbils (tiny secondary bulbs that forms in the angle between a leaf and stem or in place of flowers) which help it to spread, particularly where animals such as dogs, deer or even people carry them to new areas on their feet. It is very invasive to the detriment of the native plants and has been declared as one of the plants that is illegal to allow to grow in the wild but is extremely difficult to eradicate.
It was introduced into cultivation in 1823 and first recorded in the wild near Edinburgh in 1863 and is becoming common especially in eastern and southern Scotland, unlike the Three flowered leek (Allium triquetrum) found mainly in southern Britain.   Like Ramsons it can be used as a vegetable.
