Greater plaintain. Edible, but not very tasty. Mostly used as a medicinal herb for a variety of maladies including liver cleansing.
Colts Foot: Leaves can be cooked and eaten, but contain a liver damaging alkaloid and should therefore only be consumed in moderation. The yellow flowers appear before the leaves and disappear again before the leaves come out. A tea made from the flowers and leaves relieves coughs
Golden Rod. An aromatic herb, a tea made from the flowers and leaves helps with various maladies of the water system, i.e. cistytis, kidney trouble etc.
Oak. Acorns themselves are edible, but need repeated boiling to reduce the bitterness so are not really an option. Young leaves are edible though and a palatable wine can be made from them
Comfrey. Again not recommended for those with liver trouble and should be consumed in moderation. My favourite way of eating comfrey leaves is covered in a tempura batter dipped in soya sauce. The health benefits of this plant probably outweigh potential harm caused by alkaloids.
Wild strawberry. Also the leaves are edible and go into my spring tart alongside primroses and sweet violets.
...and....(drum roll...), well done Tanya, butcher's broom. The berries aren't poisonous as such, but will give you the runs. Young shoots are edible like asparagus. The seeds can be made into a coffee substitute. But the main function is medicinal. The roots used internally and externally are a cure for varicose veins and hemorhoids.
Nobody got the bonus plant, but hey, maybe it's just a useless weed, although there aren't many of them... Well done to those who had a go. Tanya, Mr.H and Ruth all managed 11 right!
