Witchhazel and the Vernal Equinox (aka. First Day of Spring)

The first day of Spring is synonymous with the Vernal Equinox, meaning equal day and equal night: 12 hours of daylight and 12 hours of darkness. The daylight hours are increasing. In the garden, Spring is marked by the emergence of crocuses, daffodils, hyacinths and eventually tulips. But another plant is blooming; Vernal Witchhazel.
