Galanthus 'James Backhouse' is a vigorous, early-blooming snowdrop with large flowers with elongated outer petals like 'Atkinsii' but sometimes forming weirdly shaped or extra petals. The inner petals are marked by a broad, green inverted V. Snowdrops are a harbinger of spring that bloom in late winter, often breaking through the snow. Their pendulous pure white flowers often have green markings, the small subtleties of which along with the variation in petal shapes beguile many gardeners who, having fallen down the rabbit hole, are known as galanthophiles. Beware! You could be next.
