Similarly, he (like a flame) has his roots fixed in the ground from which he sucks his nourishment, as a wick does with his tallow, wax or oil, substances that cause them to burn. The trunk that sucks its juice or sap is the same as the wick on which the fire is maintained by the fluid it sucks into itself - and the white flame are its branches and haluzas, strewn with leaves; flowers and fruits, which is actually the ultimate meaning of tree life, are white flames where everything transforms.
(Baise de Vignére, from Candle Flame by Gaston Bachelard)
Gaston Bachelard writes about how the fire that burns breaks out of trees and flowers, and Jamie Olivier teaches children in England what vegetables look like. We feel that the more we try to civilize, the more we lose contact, and not just with nature. I am thinking of my grandparents, who took life simply, but knew every branch in the area and everything they needed was provided by themselves. Today we are surrounded by things that we can use, but we have no idea how they originated or how they work.
