Oriental Bittersweet: November Fruit

When the bright red and gold leaves of the Fall have fallen by the middle of November, there remains another red and gold attraction in Eliza Howell Park: the fruit of the Oriental Bittersweet.

Though there are still a few remaining honeysuckle berries that the birds have not quite finished, bittersweet can be considered the last fruit of the season. As recently as September, it showed little indication of the starring role it would later play.

Oriental Bittersweet is a vine that was brought to this country in the 1800s and has now spread widely. There is also a native North American Bittersweet vine, but the ones that I watch in Eliza Howell are the Oriental variety. It grows and spreads rapidly and can climb dozens of feet. The next picture shows the twinning nature of the vine; the following one gives an indication of its ability to climb trees.

The outer seed covering totally hides the fruit inside until late Fall. Birds are not attracted until the outer shells begin to open, allowing access to the red fruit, usually after the bittersweet leaves have already fallen.

The gold shell, which opens in three parts, remains attached for a time (contributing to the attractive red and gold look) and later drops to the ground. The red fruit may hang on well into winter.

Though Oriental Bittersweet might make for an attractive home decoration at this time of the year, people are rightly advised not to pick and transfer. Unless the seeds are very carefully disposed of, new plants could sprout, spreading the aggressive and hard-to-control vine. It is considered an invasive plant that may damage the environment.

The word “bittersweet” means pleasure accompanied by some negative feelings, sweet with a bitter aftertaste. The pleasure of seeing the red and gold fruit of Oriental Bittersweet can indeed be a bittersweet experience.
