Tree of Life (Winx Club)

The Tree of Life (Flower of Life in Season 2) is a magical tree seen in Winx Club.

Overview
The Tree of Life holds the positive and negative balance of magic and initially grew in the Pixie Village, till the Pixies seemingly moved their village somewhere still near the Tree, from where they, along with Ninfea, guard it. Inside of it flows all the magic of the Magic Dimension, containing both positive and negative magic which coexist in harmony, and the tree glows and grows thanks to this balance between the positive and negative energy within it. Each branch corresponds to a world, and each leaf to a fairy.

Season 2
It first appears in Season 2 as a flower-like plant from which the pixies are born. Icy froze it and the plant got sick. Sometime after, the pixies asked Flora to help, but she was afraid that if she makes a mistake, she could accidentally kill the plant and destroy the pixie race from existence, but with help and aid of Helia, Flora managed to heal the plant and save the pixies.

Season 4
In "The Tree of Life," the Winx go to it to find the location of the last fairy on Earth. One of its branches corresponds to Earth, and was empty for a long time, with only one leaf remaining, standing for the last fairy on Earth. Flora used her powers to communicate with the Tree and finds out that the last fairy on Earth, Roxy, is in Gardenia.

When the Winx defeated the Wizards of the Black Circle, new leaves started growing again on it showing that Earth was ready to welcome new fairies.

Season 6
In "Legendary Duel", Aisha frees it from the Legendarium World. It is then seen in the real world after she and the pixies return to the real world.

Magical Adventure
The Tree appears again in the second movie, where it is show that half of the Tree contains positive energy, with leaves and flowers standing for Fairies, and the other half contains negative energy, with curled branches.
