Tina Celerina is the best friend of Petunia Rhubarb. She often does her best in assisting Petunia with her plants, and she is especially relied on to plan parties, though she once learned that poor planning can lead to disaster when she was completely unprepared in planning the parties of both Junior Asparagus and Archibald Asparagus.
Tina Celerina, as her name implies, is a stalk of celery with blue eyes, wears a yellow shirt with two dark blue horizontal stripes, and has her leaves tied in a ponytail.
