What is the difference between Shamrock and Clover?

The word shamrock comes from seamróg, which means “little clover” or “young clover” in the Gaelic language. So Shamrock is clover yes…. but not ALL shamrock is clover. And not all clover is shamrock. Confused yet? Perhaps it is first best to start with how to spot a real shamrock.

How to spot a shamrock

1. Shamrock is a plant that always has three leaflets in one leaf, never four. This is known as being a trifoliate plant. The story goes that this structure is why St. Patrick used it as an example of the holy trinity - three separate parts making one whole.
2. Shamrock is typically green but it can have touches of white, yellow, or even purple
3. Shamrock is the national flower of Ireland, even though it isn’t really a flower. So you are sure to spot it on national athletes' jerseys, flags, coins, lamp posts, the national airline, and many other places in Ireland besides.
4. Shamrock can be one of many plants known as clover, but types of wood sorrel are also recognized by many in Ireland as shamrock too. And there is still no consensus over the precise species of plant that is the "true" shamrock. So best stick to the first 3 criteria for spotting shamrock

How to spot Clover?

1. Clover is a plant that can have two, three, or four leaflets, in one leaf. Only the three-leaved variety is known as shamrock.
2. Most people know clover as the “lucky” four-leafed variety. This variety is because of a rare mutation with only 1 in 10,000 with this four-leaf form - hence the association with luck.
3. Clover typically grows in clumps in grasses and meadows. Bees love the nectar from this plant and you will see them buzzing around clumps of clover early in the season each spring.

So what is the difference?

There are a few distinctions, but the most important is the number of leaflets. Clover can have two, three or four leaflets. Shamrock always has three. Shamrock can be clover, but it can also be a type of wood sorrel. So perhaps not so tricky after all?
