Galanthus (convolute). He merged "Nivalis" and "Plicati" into series "Galanthus", and divided "Latifolii" into two subseries, "Glaucaefolii" and "Viridifolii" . Early molecular phylogenetic studies confirmed the genus was monophyletic and suggested four clades, which were labelled as series, and showed that Davis' subseries were not monophyletic. An expanded study in 2013 demonstrated seven major clades corresponding to biogeographical distribution. This study used nuclear encoded nrITS (Nuclear ribosomal internal transcribed spacer), and plastid encoded "matK" (Maturase K), "trnL-F", "ndhF", and "psbK–psbI", and examined all species recognised at the time, and also two naturally occurring putative hybrids. The morphological characteristic of vernation that
Flower garden garden. It is usually only a feature of large residences. The cutting garden is typically placed in a fertile and sunlight position out of public view and is not artistically arranged, as it contains flowers for "cutting". The cutting garden may comprise a herb garden and ornamental vegetables as well. Flower garden A flower garden or floral garden is any garden where flowers are grown and displayed. Because flowers bloom at varying times of the year, and some plants are annual, dying each winter, the design of flower gardens can take into consideration maintaining a sequence of bloom and consistent
