Galanthus leaves (vernation). In the era of molecular phylogenetics this characteristic has been shown to be unreliable and now seven moleculary defined clades are recognised corresponding to the biogeographical distribution of species. New species continue to be discovered. Most species flower in winter, before the vernal equinox (20 or 21 March in the Northern Hemisphere), but some flower in early spring and late autumn. Snowdrops are sometimes confused with the two related genera within the tribe Galantheae, snowflakes "Leucojum" and "Acis". All species of "Galanthus" are perennial petaloid herbaceous bulbous (growing from bulbs) monocot plants. The genus is characterised by the
Flower garden 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 color combinations through varying seasons. Besides organizing the flowers in bedding-out schemes limited to annual and perennial flower beds, careful design also takes the labour time, and the color pattern of the flowers into account. The labour time can be decreased by using techniques such as mulching, companion planting, use
