— Rhizome was born of the fascination of Pierre Bonnefille for a collection of Ikebana Japanese baskets. These flower baskets bear witness to the ancient traditional art of woven bamboo that attained its height of perfection during the Meiji Era (XIXth century). The bamboo is used in its entirety from the stem to the root, weaved, knotted, twisted, and becomes this small masterpiece in plant form. 

​

— Through slow permeation, this object led the artist to adopt a form taken from the "root" handle of this basket, which was significant in the creative process.  This root, which is both fluid and sinuous, carries the memory of the energy necessary for it to trace its path in the earth. It is matter and movement 

​

— Representing poems on the energy of plant life, creations from this series have obvious sculptural characteristics. First sketched with a brushstroke, the slender shapes finally come together around a block and giving the objects of this series a particular internal tension. 

​

— Monochromatic work, Pierre Bonnefille works the surface in successive layers using crushed charcoal powders which tint the material in the mass.
