Clover: Why We’re Featuring This Plant

First of all, we’re featuring this plant for it’s significance to the “holiday” known as St. Patrick’s Day.

As you may know, green beer and such are Americanized additions to centuries-old Irish traditions. However, Clover does celebrate its roots in the Northern Hemisphere.

In addition, clover, or shamrocks, are historically significant to Ireland. But, how exactly did this plant become a national symbol for a whole country?

Did you know that clovers can also be found with four leaves? These are truly rare and thus considered “lucky charms” by the Irish. Sometimes clovers can even be found with five, six, or more leaves!

It’s often said that Ireland is home to more four-leaf clovers than any other place, giving meaning to the phrase “the luck of the Irish.

Finally, we’re featuring the clover because of its health benefits and importance to the farming industry. Plus, the pollinators love clover!


Clover Flower: History and Uses

Clover Family

Clover, or Trefoil, is in the Fabaceae family. Also known as the legume family, they are an economically important family of flowering plants which include trees, shrubs, and perennial (or annual) herbaceous plants.

With over 300 known species, most clover has the iconic triple leaf arrangement, but some clover can have more than three leaves.

Other members of this important family include peas, chickpeas, soybeans, lentils, alfalfa, and acacia to name a few.


Clover Symbolism and Brief History

Three-leaf clovers often called shamrocks are symbolic to the Irish for several reasons some of which include Druid mysticism, Saint Patrick, and an Irish Revolution in the 19th Century.

To be clear, we should mention that there are two specific species of clover general accepted as true shamrocks: Trifolium dubium (lesser clover) or Trifolium repens (white clover).

Unfortunately, what most people think of as “tradition” on St. Patrick’s Day has nothing to do with the roots of the day.

Saint Patrick is believed to have died on March 17th, in the year 461, so that is a connection.

However, Saint Patrick was not even Irish; he was English. Furthermore, there is nothing uniquely Irish about shamrocks as they are found throughout Europe.

Holiday irony at its best.

First, we travel back to medieval history to the time of the Celtic priests, also called Druids. In brief, they believed that carrying a shamrock would help them see evil spirits coming so they could escape to safety.

According to legend, the shamrock was a sacred plant to the Druids of Ireland because its leaves formed a triad, and three was a mystical number in the Celtic religion.

Next, our brief history continues with Saint Patrick, a Christian priest and patron saint of Ireland. Ever heard of him?

To Saint Patrick, the clover was regarded with high esteem simply due to its appearance. Its three-leaf structure, also called trifoliate, helped symbolize the Holy Trinity in Christianity.

As Irish legend states, Saint Patrick used a shamrock to explain the concept of the Holy Trinity to the Pagan Irish in order to convert them to Christianity in the 5th Century A.D.  Later, Saint Patrick died on March 17, 461.

Finally, centuries after the legend of Saint Patrick, the Shamrock took on meaning as an emblem in the political struggle of the Irish people.

It wasn’t until the 19th century that the shamrock gained popular acceptance as people began to wear it as a symbol of unity and a national emblem for Ireland.

As you can see, shamrocks are kind of a big deal for numerous reasons.


Clover Cover Crops

Red Clover

Red clover has been used as a cover crop for years. It is winter hardy, low-cost, and readily available in much of the U.S.

Farmers use this legume to feed their livestock because it is high in protein, phosphorus, and calcium.

In addition, this type of clover acts as an amazing nitrogen fixer which could improve the quality of soil overall.

This type of clover, in addition to white clover, can also be used as a living mulch.

Crimson clover is a type of clover plant used for crop rotation as explained in Spoken Garden's

Crimson Clover is a great cover crop due to its ability to act as a nitrogen fixer in the soil

Furthermore, Red clover has important uses in the medical industry, like cancer prevention.

Crimson Clover

Crimson Clover, not to be confused with Red Clover, is also used a cover crop in gardens and farms.

Similar to Red Clover in its benefits, Crimson Clover can be planted and used during the fall and winter months to let gardens rest and revitalize their soil.   

By planting Crimson Clover in the late summer to early fall, winter weeds can be suppressed and soil fertility can be improved due to this plant’s nitrogen-fixing abilities. 

When used and planted correctly, garden soil for spring crops can be ready to use right away.

If you do plan on planting Red or Crimson Clover as a cover crop in your vegetable garden, you will need to sow seeds 6-8 weeks prior to the first frost date. 

Cover crops will keep your garden semi-active during the down-months and have it primed for your spring crops to burst with growth
