The shamrock is so heavily associated with Ireland’s heritage and history that it is often called the unofficial symbol of Ireland. Enjoy learning something new today and discovering some information that you can enjoy yourself as well as using for the educational purposes of children who are being either home or school educated.

1: Shamrocks Only Have 3 Leaves

Lots of people confuse the shamrock with the so-called lucky four-leafed clover. These plants are not quite the same thing. Although they are both clover, they are different because of the number of leaves and the associated meanings that are given to the plants based on this.

Both the shamrock and the four-leafed clover come from the white clover plant. This plant normally has only three leaves that come off from each stem. Trifolium Repens is the scientific name for this plant and Trifolium means "three leaves." The four-leaf version is a rare variation or mutation of this clover and is therefore much harder to find. In fact, there are also five-leaf clovers and more which are also rare.

Shamrocks Are Lucky but 4-Leaf Clovers Are Even Luckier

It is said that you may find just one four-leaf clover in a patch of 10,000 normal three-leaf clovers. When you see white clover, why not look through it and see.

2: A Shamrock is Not the Official Symbol of Ireland

This three leaf clover called the shamrock is one of the most widely recognized symbols of Ireland and is often referred to as the unofficial symbol of this country. The official symbol is actually the Irish harp instead.

Many people take one glance at the shape and the green color of this plant and then immediately identify it with Ireland. The shamrock is referred to as the national plant of this country which lies off the west coast of England. It is normally worn with much pride as a symbol on St. Patrick’s Day. This occasion falls on March 17th each year.

3: What the Plant Name Means

The name for the shamrock originates from the age-old Irish word "seamrog." This word is translated in some cases to mean "summer plant," which makes sense because white clover is prolific in the summer months. You often see bees all over it. The name also comes from the Gaelic word to mean "little clover."

4: Why St. Patrick is Associated With the Shamrock

When Saint Patrick traveled over to Ireland in the fifth century and began preaching the word of God, there was a small problem. Unlike today, Christianity was traditionally spread around by word of mouth. Armed with this knowledge, this Saint is said to have used the shamrock and its distinctive three leaves to teach the people all about the Holy Trinity: the Father, the Son, and the Holy Spirit.

Saint Patrick Used the Shamrock to Teach of the Holy Trinity


Saint Patrick showed the Irish people that while the parts of the Holy Trinity were each separate entities, they were also all connected together as well. It is the same with the shamrock because it has three separate leaves which growing and then branch out from one single stem.

We still do not know for sure whether the connection between this Saint and the way that he is said to have taught with the clover is actually true. However, it is certainly a good story nonetheless. It does make sense that a three-leaf clover is a symbol of the Holy Trinity.

5: How Shamrocks Became so Famous

Eventually this plant came to be regarded as something holy. It came to represent the teaching of the man turned Saint who had come to preach the word of God to all people. It is widely believed that Saint Patrick also suggested that the shamrock would offer a bit of luck.

For these reasons and also the religious connotations too, the symbol and motif of this wonderful plant is often displayed proudly in Irish parades and celebrations. It is a plant and a symbol that is well loved by the people of this charming country.

6: Why the Shamrock Has Not Always Been a Good Symbol

The meaning of symbols can often change throughout history and sometimes rather dramatically too. In the early 1900’s, the shamrock became a symbol of rebellion of the Irish people against the English. As a symbol of rebellion, openly displaying this three-leaf clover was made illegal and punishable by death.

7: Why Shamrocks Were Important to Ancient Druids

This plant isn’t just connected with Irish Christianity either. Druids are said to have thought that this three-leafed clover was actually a lucky charm to ward off any evil spirits. They also thought it was holy because the three leaves form what is called a triad which was important to their beliefs.

The Maiden, The Mother and The Crone is a druid concept that the Shamrock was believed to represent. The shamrock was a lucky symbol because it had 3 leaves.

This triad symbol is derived from the ancient and Pagan belief that earth and water are representative of a goddess. This goddess encompasses every stage of a woman’s life: the Maiden, the Mother, and the Crone. The triad is a design of three interlocking and overlapping oblong shapes with a triangle in the middle. This is symbolic and stands for the goddess who embraces all three of these particular female entities.

8: Why 3 Leaves are a Symbolic and Special Number

The very concept of threes is vastly important in Celtic symbolism. Most Pagan religions regard the number three as being holy because of the numerous philosophies and states of being which can be applied to it. Positive, neutral and negative is one. Masculine, neutral, and feminine is another. Maiden, mother, and crone is yet another.


Three was an important number in Celtic mythology and history. This is an ancient Triskelion Symbol carved into stone.

Three is representative of luck in so many religions and specifically in Celtic Druidism, which predates Christianity by many thousands of years. So we can see why a naturally growing plant that had three distinct leaves was going to be so important to faiths and religions where this number really stood for something.

9: How the Shamrock is Still Used in Weddings Today


Shamrocks are often placed as a lucky emblem and motif in the wedding bouquet of an Irish bride. This is an old custom and tradition that is still often followed today in modern weddings.

10: You Can Grow Your Own Shamrocks

The shamrock is said to be a fairly easy plant to grow, and you can get them as seeds or bulbs. If you plant these indoors around early January time, then you could get a nice little growth by the time that St. Patrick’s Day comes around in March.
