LOOK FOR: Spicebush Flowers, North America's Answer to Forsythia

Along one side of our yard, our neighbor has a forsythia hedge whose cheery yellow flowers are a magnificent joy in spring. But you won't find forsythia in the woods (at least, not yet):  it's from China. Instead, we look every year for the less showy but equally cheery flowers of the spicebush as they emerge to light up the understory of our local forests. On our hike yesterday, they looked like they were ready to burst open any day now.

For us, spicebush is a way to mark the passing of the seasons. We wrote about spicebush last September, when the bright red berries were marking the beginning of fall. Now is the time to look for the flowers that create those berries: they're a harbinger of spring (and much more reliable than groundhogs).

The flowers of spicebush appear in clusters along the stems, before the leaves emerge. Each flower has five small petals. (For comparison, forsythia has only four petals per flower. So does witch hazel, whose wispy yellow flowers otherwise can seem quite similar -- except that they bloom over the winter.)

Between the early spring flowers and the vibrant red berries, we're mystified as to why spicebush isn't a more common plant in yards and other ornamental plantings. It also has high wildlife value -- it serves as a host plant for beautiful spicebush swallowtails and promethea moths, while the berries feed birds and other critters.

The spicy twigs and berries of spicebush (think allspice) also have been used by humans for teas and flavorings for centuries (maybe millenia). They aren't attractive to deer, though -- which likely explains why spicebush remains common in our local woods even as the out-of-balance deer population is stripping out most of the rest of the understory.

If the deer are going to leave us just one shrub, we'll take spicebush, and with pleasure. It's a great way to greet the spring.

In the wild: Spicebush is one of our dominant understory shrubs.  One of the most impressive areas we know is in Rock Creek Park, in the section east of Boundary Bridge. But you'll probably see some spicebush in just about any woods in the DC metro area.

In your yard: Spicebush needs shade, but a few hours of sun will encourage them to flower more and set more fruit. They can also suffer if they get too dry, especially as they're getting established -- they'll do best with reasonably moist soil.

I'm glad you could use my photo.

I love spicebush, and I was so excited when I was able to get this one and plant it in the backyard. You might like to know that this particular bush lives in Falls Church, VA, even though I no longer do. That makes it a neighbor of yours, sort of.

I've been slowly replacing all of the aliens previously planted on my property and forsythia is one of the few I have left. Don't know why I didn't think of spicebush as an alternative. Thanks for the advice!

Thanks for the info on spicebush. I just discovered that I have two of them growing in the woods behind my house. Yay!

I'd love to plant one in my yard. Where would I go to buy one?

You could call Behnke's and see if they've got any -- I've seen them there before. Also, tomorrow (3/26) is a native plant sale at the National Arboretum -- folks are sure to have some there.
