As we enter late autumn in the Upper Delaware River region, the forest palette is suddenly bereft of the colorful explosion of fall foliage that for weeks kept us enthralled. In truth, the far more subtle tones of the December landscape are also satisfying.

One plant is particularly striking at this time of year, standing out in stark contrast to the muted forest where it climbs and clings to trees, wrapping them in a vise that sometimes costs them their lives, in a showdown that is both treacherous and attractive at once.

Bittersweet, then, seems aptly named. The dubious charms of this vigorous vine echo the reality we face at this time of year when all that is fading and collapsing back to Earth takes on a sere beauty of its own. We are obliged to relinquish the expansive energy of summer and turn toward the inward seasons of fall and winter.

Be aware that there are two vining plants commonly called bittersweet. Both provide beauty while taking a toll on forests. American bittersweet is indigenous to North America and bears smooth stems. Unfortunately, a very similar vine whose stems feature blunt thorns, known as “oriental bittersweet,” has become one of North America’s most invasive plants. Oriental bittersweet is native to eastern Asia and outcompetes American bittersweet and other vegetation by engulfing and slowly killing it.

Avoid planting oriental bittersweet at all costs. And before intentionally growing American bittersweet, consider both its darker and brighter qualities. Once it is established, this hardy vine is difficult to eradicate.
