Invasive Bittersweet

In the annals of color there are innumerable greens. There are countless shades and hues of red. There is a rainbow of yellows: ictarine, mustard, ochre, lemon, and saffron. There are mysterious purples which haunt the imagination and are as different from each other as day from night. Then there is orange. For some reason, there are not a great many different named varieties of orange. Ferrebeekeeper has blogged about safety orange (international orange) which is used for marine rescue equipment and experimental aerospace equipment. Then there is coral, vermilion, and tangerine…and after that the oranges are a bit thin on the ground.

Part of the reason for this paucity of orange vocabulary is that pale oranges tend to be seen as flesh colors, and dark oranges are styled as “brown”. However there are also some orange colors which are quite lovely which are only now getting stylish fashion names.

In a long-ago post Ferrebeekeeper has featured one such hue of orange: bittersweet, which is named for berry-producing vines of the woody vine family “Celastraceae.” I said berries, because the glowing pinkish orange berries of bittersweet look like some celestial dessert fruit. Alas, the berries are toxic to people and domestic animals (although some sorts of wild animals and birds seem able to break down the eunonymin which causes such distress to dogs).

Bittersweet is grown in gardens because of the beauty of the berries. There is a native bittersweet vine in America, Celastrus scandens, however, there is an even more luminous orange pink variety of bittersweet vine from Asia named Celastrus orbiculatus. As will surprise no one, this ornamental bittersweet has escaped from the flower garden and crafting supply store and is now outcompeting the American bittersweet or hybridizing with it to make strange new wild cultivars. The story of how we have introduced a non-native vine with beautiful albeit slightly toxic berries for no reason other than their pretty color is not necessarily a story of ecological prudence or forbearance, however it does speak to the loveliness of this orange-pink.
