print [Klass.__name__ for Klass in Flower.__subclasses__()]
would be easier to understand.
Somehow it doesn't feel right to define
__repr__ as only self.__class__.__name__
since repr() is normally used as the inverse of eval().
Did you consider defining __str__() instead?
Btw. thanks a lot for TIJ.
P.S. Did they really make __subclasses__() a method?
