Botanical Classification and Taxonomy of
- Rosa × englishe roseum*
Taxonomic Classification
The full taxonomic classification would be: Kingdom: Plantae; Division: Magnoliophyta; Class: Magnoliopsida; Order: Rosales; Family: Rosaceae; Genus:
-Rosa*; Species
(complex hybrid, parentage unclear); Cultivar:Rosa × englishe roseum*. Note that the species designation remains ambiguous due to the hybrid nature of the plant. The “×” symbol indicates that it is a hybrid, a result of deliberate cross-breeding of different rose species or cultivars.
Historical Origins and Breeding History
The precise breeding history of
- Rosa × englishe roseum* is often undocumented for many older cultivars. Many English roses, to which this cultivar likely belongs, resulted from complex breeding programs spanning decades, involving crosses between various
- Rosa* species, including
- Rosa rugosa*,
- Rosa wichuraiana*,
- Rosa foetida*, and various
- Rosa gallica* and
- Rosa centifolia* descendants. These breeding programs aimed to combine desirable traits like strong fragrance, repeat flowering, and disease resistance. The specific parent plants of
- Rosa × englishe roseum* are not usually documented in detail. Records of its creation, if they exist, are likely held within private collections or horticultural archives.
Comparison with Related Rose Cultivars
Rosa × englishe roseum*, being an English rose, shares characteristics with other cultivars in this class. These include abundant blooms, a strong, often old rose fragrance, and a generally bushy habit. However, specific traits like flower form, color, and disease resistance would vary from other English roses.
Comparisons would need to be made against specific cultivars to highlight unique characteristics. For example, it might have a more compact growth habit than ‘Gertrude Jekyll’ but a less intense fragrance than ‘Abraham Darby’. The differences would be subtle, often reflecting nuances in genetic makeup from the various parent plants involved in its creation.
