The symbol of Ireland. The Shamrock isn’t actually a species. The name comes from the Irish word Seamrog which literally translates as little clover.
There have been two serious botanical surveys to try and find out what a Shamrock is, both surveys involved asking people from across Ireland to send in samples of Shamrock which were then potted up and their species determined.
About half of the respondents voted for this species.
Trifolium dubium, Lesser Clover or Lesser Yellow Trefoil.
The leaves are what they term a survival food and that just means that there isn’t any point in eating them. They won’t kill you they just don’t taste very nice.
The flowers are completely edible and add a nice bit of colour to dinner.
Now I have just got to find a four leafed one.
