Satyr tended a garden in the Dreaming until Redcap destroyed it and killed Satyr. When Satyr returned he planted the Tree of Life where the garden had once stood.
Here is one telling of that tale (originally written by Svend Andersen):
In the timelessness of the Dreaming, Satyr found a secret place, far away from everyone else, empty except for the ripples of Dreams and the footprints of Eshu. So he decided to make a garden there — and the garden he made was a wonder to behold, full of beauty and peace.
And after that, when Satyr was frustrated or teased, he would go to the Garden in the secret place, and everything would be all right. But Satyr didn't want to let anyone else find his secret place, because then it wouldn't be his alone, and he would have to share the beautiful garden. So every time he went, he made sure no-one watched him, and for a long time he was able to sneak back and forth with no-one noticing.
But one day, when Satyr had slipped away from the others, he found Pooka, sitting in the middle of the garden, staring at an enormous yellow flower. At first Satyr wanted to yell at Pooka, and throw him out; but then he noticed Pooka was smiling and crying at the same time. And Satyr felt ashamed at his selfishness, and decided that what he really should do is to let everyone come and enjoy the beauty of his garden.
So all the Fae came to the secret place, which was secret no more, and all of them marvelled at the beauty of the garden, the sweetness of the fragrances, and the wonder of the flowers. It was a marvelous creation, everyone agreed, perfect in every way. And Satyr was so full of pride that he thought his heart would burst.
So time past, and the garden remained the same, as beautiful as ever. And one day, Satyr decided that he would return to the Gardens that were secret no more, and enjoy the others praising its beauty. However, when he arrived, the only other Fae there was Redcap. And Redcap was not lying on the grassy lawns, nor sniffing at the beautiful flowers, nor admiring the handsome trees. No — Redcap was eating, devouring the bright green grass, wolfing down the fragrant blossoms, tearing limbs off trees and stuffing them down his gullet. More than half the garden had disappeared into Redcap's jaws! Satyr wailed, and rended his hair, and battered Redcap with all his might -- but all in vain. Redcap devoured the whole garden, leaving the secret placce that was secret no more as bare as when Satyr had first found it.
"Why did you do it?" cried Satyr, eyes red and streaming with tears. But Redcap turned to Satyr, and his eyes were blacker than the deepness between the stars, and his mouth openned impossibly wide, and SNAP! Redcap gulped Satyr down.
Now, that's not the end of the story. Fae are immortal, and a year and a day after Redcap ate Satyr, out he came, trotting out of the mighty Gate of Ivory. And Satyr wasn't wailing and gnashing teeth; no, there was a skip in his step, and a twinkle in his eye. And what was he carrying from beyond the Gate? Why, it looked like a jewel — or maybe a seed...
And Satyr strutted from the gates, to the middle of the Dreaming, and they planted the seed. And up from the ground rushed a mighty tree, and it grew and grew until it covered the center of the Dreaming, and its fragrance and flowers and leaves were everywhere, more beautiful than a thousand gardens, more precious than anything seen before or since. But then, as suddenly as it grew, the tree grew old, and its leaves fell with a soft tinkling, and it's bark darkened, and it died.
And Boggan, who worries about such things, scurried up to make sure Satyr was all right. But Satyr did not seem sad, even though his beautiful tree had died so soon after planting; no, instead Boggin found Satyr grinning from ear to ear. He slapped Boggan on the back, danced him around the dead trunk of the once marvelous tree, and pulled him off in search of a drink. But as both of them left the grove where the mighty tree once bloomed, Satyr bent down and scooped up a seed.
