For humans, December is a peak month for parties. It's the depth of dormancy for most plants hardy to zone 6 and colder but, for a few contrarians, the season's short days and sharp winds are encouraging: December is their month to party, too.
Here's a stem of a Chinese shrub known in the West as wintersweet. The flowers and buds may look pale and scattered, but no matter: this plant's December celebration is about fragrance, not appearance. Spicy and sweet, to me the wafting perfume recalls carrot cake smothered in cream-cheese frosting.
Wintersweet won't debut in my own gardens until 2017; this picture is one of several lusty specimens in flower by Christmas at The National Arboretum in Washington, DC. What have I been waiting for?
