Astera

The aster is a distant cousin of the thistle that is found in the French countryside. It's a wild flower that has adapted to the urban environment, where it can grow up to a height of ten metres.
The aster is an intriguing, silver-coloured plant that shimmers and shines during the day but that transforms into a bewitching creature at nightfall, when its core distils a thick cloud of florid beams that bathes its prickly spine in light.
But the aster is also a flower of the night boasting a very special form of photosynthesis, blossoming at sunset when it reveals all its beauty as it is decked in an infinite number of brilliant colours.
