ROSES or rosehips, form a genus of plants, the genus
Rosa of the family Rosaceae, originating from the temperate and subtropical
regions of the northern hemisphere. They are shrubs and shrubs, sarmentous and
thorny. According to the often diverse opinions of botanists, the Rosa genus
comprises from 100 to 200 species that easily hybridize with each other1.
Several species and many cultivars, derived from mutations or
crosses, are grown as ornamental plants for their flowers, roses. These are the
largest category of cut flowers, sold at florists2, but roses are also grown
for the production of perfume gasoline.
Botanical classification of species
The genus Rosa is divided into four unequal subgenera, three
of which comprise only one or two species, and the fourth, Eurosa, all the
others28. This classification is largely based on anatomy but does not reflect
the evolution and phylogeny of these species.
The rose bushes
The cultivated roses are most often cultivars created by rose
growers and more rarely natural forms (species or varieties) (botanical roses).
In the case of cultivars, the provisions of the International
Code of Nomenclature for Cultivated Plants apply. These require the use of a
variety name written in a living language and not in Latin (although for some
ancient varieties Latin was used) and written in Roman characters placed in
single quotation marks and starting with a capital letter. Example:
'Remembrance of Malmaison'.
In order to allow amateur gardeners to benefit from varieties
of roses of superior quality, a sign of quality in the form of a red label has
been created by the association "Plant Excellence".
Botanical roses
Botanical rosebushes are all species of wild roses with
specific characteristics and used in horticulture such as:
• wild rose hips (Rosa rubrifolia, Rosa primula, Rosa sericea
or Rosa canina which often serve as rootstock for their resistance to
limestone).
• Rosa gallica, one of the oldest species of cultivated
roses. Originally from Europe, she tolerates the cold.
• Rosa chinensis, with continuous or ascending flowering.
Native to Asia, it is a kind of hot climate.
• Rosa banksiae, Rosa gigantea, which grow in long unarmed
lianas,
• Rosa moschata, bushy and with fragrant flowers (ancestor of
the Hazelnut rose),
• Rosa multiflora, very vigorous and very floriferous,
• Rosa rugosa, very resistant to diseases.
