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 should always be in bloom. The best mixtures even include combinations of perennial and biennials, which may not bloom until the following year, and also annuals that are "self-seeding", so they will return, creating a permanent flowerbed. Another, even more recent trend is the "flower garden in a box", where the entire design of a flower garden is pre-packaged, with separate packets of each kind of flower, and a careful layout to be followed to create the proposed pattern of color in the garden-to-be. Many, if not most, plants considered decorative flowers originated as weeds, which if attractive enough would
