Black Flower Secret Garden by Yuri Catania is begun during the first lockdown in March 2020, unable to leave one's home in the heart of Switzerland in the middle of the most impressive nature between Mountains and the lake of Lugano. Flowers are grown and shot in their natural habitat (the wife's secret garden). When the flowers sleep during the long nights between 3 and 4 in the morning, with absolute silence of the deserted streets. Thanks to natural darkness and an LED flashlight, the result reveals shots with bright and deep colors, suspended in a dreamlike and intimate dimension. The project count over 100 works already exposed during 2021 in many art exhibitions in Europe like WopArt Lugano, International Art Zurich, Mia Image Milano art fair, and a solo exhibition with all the collection at Art Trust contemporary art gallery in Switzerland. The artist in exclusive for OPENSEA NFT collectors has created with UV light an "aliens" flower colors version using the ultraviolet vision.
