Friday may have been the first day of spring, but as I watched the snow cover the plants, it certainly felt like winter. I know that everyone is anxiously waiting for spring to arrive, but there is something quite perfect about witch-hazel blooms dusted with snow that demands appreciation. The Azalea Garden is full of these bright spidery flowers right now. They are not some anomaly attributed to our changing weather patterns. This is their time. When it is still gray and the threat of snow still looms large, you can count on their light and warmth in the garden.

Witch-hazels have a range of flowering times depending on species and cultivar. The American witch-hazel, Hamamelis virginiana, flowers in autumn. Vernal witch-hazel or Ozark witch-hazel, Hamamelis vernalis, is also native to North American and often blooms in winter months despite its name. However, this species typically has small flowers and a strong tendency to hold on to its leaves all winter long, obscuring its fragrant flowers. Look for cultivars that were selected for their early leaf drop. The Chinese witch-hazel, Hamamelis mollis, and the Japanese witch-hazel, Hamamelis japonica, flower in late winter. These species are prized for their large and fragrant flowers, as well as their perfect timing – just when we need them the most! The majority of selections available today are cultivars of the hybrid between these two Asian species, Hamamelis × intermedia.

A Rare Find in Bloom

The uncommonly cultivated cobweb flower (Platycrater arguta) is one of many rare Asian woodland species grown in the Azalea Garden. A hydrangea relative, this species is native to southern Japan, as well as a small range in eastern China, where it is considered threatened.

This deciduous shrub reaches about 3-4’ feet high and wide and is sure to stump many a horticulturalist with its lovely, unique blooms. Four-petaled white flowers form a balloon shape before opening to display abundant, large yellow stamens. Floral bracts persist into fall, adding texture while the leaves fade to yellow.

If you can find this plant at a nursery, it might be a perfect addition for a partial shaded, well-drained spot in your garden. At the center of the Azalea Garden you’ll find this lovely, well-behaved species in bloom right near the overlook.
