It is odd to consider that, while sunlight typically makes plants bigger and stronger, a Gloom exposed to excess sun (or sun stones) will shrink to a smaller size than an Oddish when it evolves into a Bellossom. Furthermore, unlike a Gloom's noxious odor and venom (or that of wild Oddish, although farm Oddish have had the poison bred out), Bellossom are not poisonous and extremely edible pokemon. Indeed, some have questioned if it is even an evolution at all; Gloom certainly turn into Bellossom, but to many it seems like a devolved version of Gloom, or certainly a dead end compared to a Vileplume.

Yet many trainers choose to evolve their Gloom into Bellossom, and there is a good deal of evidence to suggest that they made the right choice. Bellossom emit a sweet, pleasant fragrance which draws their opponents to them, then strike them with a powerful, point-blank Solarbeam, winning many a battle instantly. Their small size and dancing ability allow them to move around and dodge many attacks, whenever their rival either manages to regain focus or lacks a significant sense of smell. These matches often come down to the weather; against opponents of more or less equal strength, Bellossom usually win in the sun, but lose on cloudy and rainy days.

Most trainers who choose the path of Bellossom, however, do not do so for power. Instead, they do so because they find Bellossom to have a kinder temperament, a much better fragrance, and because they grow beautiful flowers which can be picked and given to loved ones. Evolution is nothing more than adaptation, and Bellossom, evolving as they do from domestic Oddish, have become a species which humans love.
