Abstract
The reference collection of the genus Hydrangea established in Angers includes now 380 accessions.
Although the main number of taxa belongs to H. macrophylla Ser., 13 species are present.
For a good management of the collection (typing of varieties, search of synonyms…) and a better knowledge of the genus, most of the taxa form the subject of a morphological study.
Data analysis have been realised on 292 cultivars of H. macrophylla Ser., 28 qualitative criteria and 5 quantitative criteria were used.
These multidimensional analysis allow us to separate and to characterise two subspecies (macrophylla and serrata) and to point out some hybrids.
