In unpublished manuscripts of 1976-1977 (also, Oxford Conference, 1976) Jean-Yves Girard introduced the concept of garden; the terrible complexity of anything connected with gardens made it necessary to lok for a simpler viewpoint. Then, in the next years he introduced and developped the concept of a dilator. Yet, in some cases, gardens may be of great interest.: a garden is shortly the functorial version of a Bachman collection in which the fundamental sequences are replaced by “fundamental flowers“. In this work we prove that there is an isomorphism between the categories of gardens and dilators.
