The Chinese people introduced the peaches in Europe, with Italy being the first import country, later spreading the peaches all around Europe. Back then, Peaches became a stylistic device for depicting realism and the fleetingness of life in art by Flemish painter Jan Van Eyck and Dutch painter Van Gogh, which has recently received a special TGC-card due to the special pokemon art at the Van Gogh museum.

The dutch are known for there painters in the "Golden Century" which is a big part of the Dutch culture, and three paintings are present in Nemona's house. One looks like Ash' Greninja, using only red, blue, yellow, and black colors, which is the style of Dutch painter Piet Mondriaan. The other one are two eevees in a landscape, and if you look closely, this painting was made in the Van Gogh style (look closely at the way the air is painted). The thirth one includes a bunch of finneon and luminieon, which look very real. The Netherlands most famous painter Rembrandt van Rhijn is known for his realistic way of paining. Brassius is also an artist and made the "Surrendering Sunflora", which is based on sunflowers (just like Van Gogh!). In the players house, more paintings can be found, such as fruit (sepcialty of Willem van Aelst), windmils (specialty of Jacob van Ruisdael), and a dancing woman (specialty of Jan Sluijters).

According to recent speculation of Gen 10 being based on The Netherlands, I think this might add up to this theory (Masuda was also in The Netherlands recently). Overall, I think this is not a coincidence!
