Add a Teacher Note to share how you incorporated it into your lesson. One clover is actually one leaf of a larger plant, with 3 leaflets. Mutations can occur due to a low frequency recessive gene or environmental causes. Often the reason for mutation is differentiable from one clover to another. The mutation does not stop at the 4-leafed variety: 5-leafed clovers are not uncommon.
However, the more leaflets, the harder they are to find and the luckier they are : the record is an leaf clover, and the highest I've ever seen is leafed.
Four-leaf Clover | Definition of Four-leaf Clover by Merriam-Webster
First, find a large patch of Clover, which isn't hard to do if you have a lawn or live near a park. Do not get on your hands and knees with magnifying glass in hand, individually examining each clover. From standing height, look over the entire patch, brushing the clover with your foot to ensure none remain unexposed.
If you enjoy math problems, eye-spys, the game "SET", or any pattern game in general, you'll be in your element.
Expertise. Insights. Illumination.
Amongst all the sets of 3 leaflets, any mutation will stick out like a sore thumb. So even though they say there is only one 4-leafer in 10, clovers, thats not entirely the whole story. One clover is just a member of one White Clover plant, which can cover from a few square inches to a few square feet.

And some plants are more susceptible to mutation than others, so if you find one, look hard in the near vicinity. Several of the mutants pictured in the following steps were all found within a few square inches. Mutant clovers are also more prevalent later in summer than they are in spring, and some places just seem more environmentally favorable to produce mutants.
The following steps show a few typical mutants so you know what you are looking for. The Classic 4-leaf clover has, well, 4 leaflets. Most mutants have three leaf stems in which one has split into two leaves, one usally smaller than the other. These types are probably produced by evironmental factors more than genetic factors not that genes don't play a part.
Clovers with 4 leaflets, evenly shaped, and 4 seperate leaflet stems are, from my experience, rarer, and probably strongly genetically influenced. Note: There are a few companies that have tried to breed 4-leaf clovers to sell for their alleged lucky properties. Due to the complications between environmental and genetic influence, these breeds are tough to produce, and only marginally effective, or so i've read. Some have the attributes of several different kinds of mutants and can be really interesting. Some clovers not very exciting, but pretty rare have a mitten shaped leaflet due to conjoined leaves.
You can tell they are conjoined by looking under the leaflet and noticing that it contains two stems see below. Even rarer: sometimes part of conjoined leaf breaks off, with a little leaf sticking like a "thumb" off the mitten sorry, no pic Some clovers will also have a "rust color". This is probably due to an inability of this clover to produce green chlorophyll in the leaflets, showing the less dominant red, yellow, or brown hues, much like how leaves turn colors in fall.
Unlike deciduous plants, however, I've noticed this discoloration through out the year. These clovers exhibit a strage shape of each leaf which reminds me of the shape of a spade. At first i thought it was due to insects, but the pattern is too perfect and insects too hungry to always produce this shape. Must be a mutant! Just kidding, someones just messing with you. Though technically, its possible.
Though tough to prove I made a simple press to collect my clovers using two pieces of scrap wood and 4 machine screws with wing nuts at each corner. I placed duct tape on the inside of the press to make it easier to slide the note cards i used to seperate and label the clovers in and out. Sticking them in between two cards in your wallet works as well, but be prepared to have your credit card number etched into a leaf.
I glued my dried, pressed clovers using a dab of elmers glue. Try to keep the mount as air tight as possible, as the clover's will loose their color over time. Last summer i put this skill to the test: i found 4-leaf clovers, 11 5-leaf, and 2 3. After mounting these, i found one patch while mowing the lawn containing multiple 7 and 8 leaf clovers, as well as a 10 leaf. All of the clovers pictured in this instructable were found in about 20 minutes of searching.
They're out there, in many mutant combinations, so get looking and get lucky! I have not found a 4 leaf clover or above after looking for 30 minutes in my school field, anymore ways to find? Reply 7 months ago. Try a different spot! I can easily find clovers in most places, but I've never found any in my grandparent's back yard. I can solve the spade leaf problem!!! When the clovers come up they're still folded and insects eat a chomp out of them since they're so tender and then they open after- like a paper snowflake!
St Patrick’s Day 2016: The difference between a shamrock and a four-leaf clover
I am thrilled to see such intrest in 4 leaf clovers! I thought it was only me. It is claimed that there are approximately 10, three-leaf clovers for every four-leaf clover. Even so, this probability has not deterred collectors who have reached records as high as , four-leaf clovers in a lifetime. The world record for number collected in one hour is , set by American Katie Borka on June 23, Clovers can have more than four leaves. Five-leaf clovers are less commonly found naturally than four-leaf clovers;   however, they, too, have been successfully cultivated. It is debated whether the fourth leaf is caused genetically or environmentally.
What’s the Difference Between Shamrock and Four-Leaf Clover?
Its relative rarity 1 in 5, clovers  suggests a possible recessive gene appearing at a low frequency. Alternatively, four-leaf clovers could be caused by somatic mutation or a developmental error of environmental causes.
They could also be caused by the interaction of several genes that happen to segregate in the individual plant. It is possible all four explanations could apply to individual cases. This means that multiple four-leaf clovers could be found in the same clover plant. Researchers from the University of Georgia have reported finding the gene that turns ordinary three-leaf clovers into the coveted four-leaf types.
Masked by the three-leaf gene and strongly influenced by environmental condition, molecular markers now make it possible to detect the presence of the gene for four-leaves and for breeders to work with it. The other leaf traits, the red fleck mark and red midrib, a herringbone pattern that streaks down the center of each leaflet in a bold red color, were mapped to nearby locations, resolving a century-old question as to whether these leaf traits were controlled by one gene or two separate genes. White clover has many genes that affect leaf color and shape, and the three in the study were very rare.
These traits can be quite attractive, particularly if combined with others, and can turn clover into an ornamental plant for use in flower beds. There are some cultivars of white clover Trifolium repens which regularly produce more than three leaflets, including purple-leaved T. This may be another plant, or another genetic mutation. Some genetic mutations in clovers include spade-like shaped leaves or a dotted rusty colour on the leaves. Trifolium repens "Good Luck" is a cultivar which has three, four, or five green, dark-centered leaflets per leaf.
Other plants may be mistaken for, or misleadingly sold as, "four-leaf clovers"; for example, Oxalis tetraphylla is a species of wood sorrel with leaves resembling a four-leaf clover. Some folk traditions assign a different attribute to each leaf of a clover. The first leaf represents hope, the second stands for faith, the third is for love and the fourth leaf brings luck to the finder. A fifth leaf represents money, but there is no meaning as yet for the sixth leaf and above. Others say that four-leaf clovers granted the power to see fairies, or that they are related to St. Patrick's use of the shamrock to explain Christianity to the Irish .
