Flower ponies

Daisy, Lily, and Rose are three earth ponies with flower-themed cutie marks that frequently appear together in the show. While Daisy and Rose are named on the show, the name "Lily" is only a placeholder name and does not appear in official material.

Daisy
Daisy gardens and runs an herb shop in Bridle Gossip. She magically lifts a branch at the beginning of Look Before You Sleep even though she lacks a horn. She shares her color scheme with suprise bag toy Flower Wishes.

Lily
Lily is the placeholder name of a pink-coat yellow-mane earth pony who wears a lily flower in her hair. Easily frightened in a number of scenes. She's had lines in Applebuck Season, Bridle Gossip and The Cutie Pox. Her cutie mark is three white lilies.
