I realized the Sunflower Tower (1986-2003) using 300 bamboo poles whose length are 4m.
Antecedent to that, I had made a lot of maquettes of the Sunflower Tower based on the Golden-mean. This attempt was the first time that I built it as an architecture which peoples can go into inside. It was amazing that the complete work was springing very much with wind blowing.
We can see many spirals on any sunflower or pine cone and we can find that any spirals consist of the Fibonacci Series(1). The Sunflower Tower is based on the same principle. The silhouette from bottom-up is really magnetic.
I suggested to the staff of the Fairchild Tropical Garden that it should be used as a hotel for Air Plants. Air Plants should like the tower structure because they can get enough sunlight and air.
This structure is not only sculptural but also functional.
