Four Leaf

I have gotten into a disagreement over four leaf clovers with someone who shall not be named. Apparently, she read somewhere that there was no such thing as a four leaf clover, that any four leaf plant resembling a clover was actually a different species.

This is not true.

At least, my research indicates that there are four leaf clovers. Other species of plant do resemble clover and get mistaken for four leaf clovers, but genuine four leaf clovers DO exist.

Of course, now said person is retracting their previous statement and claiming that's not what they said. Isn't that always the case of such arguments?
