Meet Sunshine Dust, an earth pony who takes "being one with nature" to the next level. She grows plants in her mane, and frequently holds very interesting conversations with all kinds of flora. Some might consider her a bit insane (this is probably not that debatable).
She was raised in the forest, and is very much to plants what Fluttershy is to animals… except with less shyness and more crazy.
Her cutie-mark is a full sun with a heart in the center, representing the phrase "tender loving care", something she bestows readily on nature, but more recently in her adventures in pony society to those she cares about." - Jittery-the-dragon
