One of the biggest wonders of Frankfurt is the Palmengarten: A botanical paradise, a perfect oasis for a busy city. It breaths well-being and there must  be a group of dedicated gardeners working behind the scenes of this living splendor. Tasmanian ferns lead to African mangrove, prairie flowers to cactus deserts, rose gardens to blooming lilies.
On one special day each year the gardeners hold their breath. When the Light festival (Lichterfest) takes place the doors are thrown open for the general public seduced by adolescent dance parties, classical dancing sessions and pop/rock performances. And there, where no one is allowed to walk on every other day of the year, visitors place candles in large patterns on the lawns. The night is lit with thousands of lights. And the gardeners work overtime protecting the botanical gems of whose worth normal mortals have no inkling.
