Wild arum berries

 All that is left of the wild arum or cuckoo pint is the clump of berries, green at first, ripening through orange to a shiny red.   

You can see why wild arum spreads so easily.  The berries are close to the ground and, once ripe, don't have far to go to meet the soil.

They look rather evil and are slightly poisonous if eaten but don't taste good, so are not very tempting.

Next spring the arrow-head leaves will pop up in January,

followed by the flowers in April.
