Are there "Identical Twin" plants?

Cloned plants would genetically identical. One can theoretically raise an
INFINITE number of genetically identical plants. Mind boggling, isn't it? It
is being done all the time.

The rest depends on how they were raised. Genetically identical plants grown
under different conditions may outwardly look different.

The old nature verses nurture argument?
