I'm very familiar with the phenomenon. It is called a "point"
mutation. The cells of the flower originate from a central point and
progress outwards from cell division. If some cell mutated during this
process, then all cells from that point forward carry and perpetuate
that mutation. If the wedge originates from the central part of the
flower, then it may possibly also be in the gametes and carry into the
cell gamete and be fertilized and be perpetuated.

In this case the mutation removed the anthocyanin wash in the wedge so
you see the underground colour.

The flower could be called a chimera in the sense that it contains two
different types of genetic material, but term is usually used on
plants that have a more randomized pattern and is scatted throughout
the plant rather then being so localized.
