A pot of four leaf clovers

Four leaves good luck

At a plant market...

Owen: A bunch of four leaf clovers? Genetically engineered, surely.

Prunella: Not genetic. Natural selection.

Owen: Darwinian culling? Perhaps inbreeding?

Prunella: If you will.

Owen: Will they proliferate?

Prunella: Don't keep them in the pot. Plant them in a garden. More will appear.

Under natural conditions, one four leaf clover occurs among 10,000 three leaf clovers. That is said to bring luck. Buying a punnet of genetically manipulated or selectively grown four-leaf clovers ... could this be called pushing your luck?
