Galanthus 'Ophelia' is a double snowdrop with narrow outer petals with a hint of green on the tips and a double centre of about 12 large petals with bold green markings. 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.
