Floret

Used in a sentence:

• As the plant slowly turned to aim itself at the rising sun, the florets attached to the stem adjusted minutely and opened their petals in order to soak in the energy they would later unleashed upon unsuspecting invaders.

Commentary:

So the definition is something left to be desired. Florets are the name of the individual flowers that might be attached to a single stem. Roses do not have florets but chrysanthemums and lettuce do. I think the term is also used as a naming convention so one might say that a rose is not a floret but is a flower, where as chrysanthemums are flowers but also florets. Confusing huh? Definitely a weird word.
