In North American commerce, the invasive oriental bittersweet (C. orbiculatus) is commonly sold as our native C. scandens, so it's important to be able to tell the difference:

1) C. scandens has orange to red outer fruit casings. In C. orbiculatus, they are yellow.

2) C. scandens bears its flowers and fruits at the tips of secondary branches only. In C. orbiculatus, flowers and fruits are borne in the leaf axils.

Wherever it occurs, oriental bittersweet commonly hybridizes with our native bittersweet, and the hybrids are like the invader. The native species is being hybridized out of existence.

I've only seen this American species three times so far over many years, twice in northern Illinois and once in Pennsylvania, planted and not wild. It is a fast growing, powerful liana or woody vine. It needs a strong support and can twine around other plants easily, so keep it sort of isolated. Its leaves are not so rounded as the similar Oriental Bittersweet and its flowers and fruits are borne terminally rather than more laterally as the Asian species. In the Mid-Atlantic the Asian species is very invasive everywhere and can kill trees by twining around them. There have been warnings that sometimes conventional nurseries are often selling the Oriental or a hybrid with the Oriental species rather than the pure American. Best to buy at native nurseries, as Prairie Nursery in Westfield, WI... read more

When I was a kid bittersweet grew all over our farm. It was a great way to hide old equipment, rolls of old fencing, and other things that tend to accumulate around the farm -- just move it to the hedgerow and a year from now it will be covered with bittersweet.

I have also seen bittersweet growing in 2nd and 3rd generation woods, where it can reach 'Tarzan' proportions. In cultivation it would need a very sturdy support, such as one would have for wisteria, due to the size and weight of the vine.

I don't see bittersweet much anymore in Southeast Michigan, which is too bad. As far as I know I have never seen the oriental species.

In the U.S., American Bittersweet is a native plant that is becoming endangered. Oriental Bittersweet is it's non-native, horribly invasive look-alike. DO NOT PLANT ORIENTAL BITTERSWEET. It is destroying native plants and the wildlife that depend on them. Be sure you have American Bittersweet.

Here's how you tell them apart:
"American bittersweet produces flowers (and fruits) in single terminal panicles at the tips of the stems; flower panicles and fruit clusters are about as long as the leaves; the leaves are nearly twice as long as wide and are tapered at each end. Oriental bittersweet produces flowers in small axillary clusters that are shorter than the subtending leaves and the leaves are very rounded. Comparing the two, American bittersweet has fewer, larger ... read more

Although C. scandens is our native it readily hybridizes with the invasive C. orbiculatus, so no matter where you live it is not advisable to plant new plantings of it. This hybridization will only create MORE of the invasive plants. :-/

I planted two vines of Celeastrus scandens 'Indian Brave' and 'Indian Maid' about 10 years ago. They are about 25ft tall now and look great.

I especially like the way the bark looks as they get big. The birds like them for shelter but I don't know how much use they make of the berries. I do have some reseeding but little vines are easily moved or pulled.

This is a native vine and there is no problem planting it. They are not considered invasive and I think many people confuse them with the oriental bittersweet which is rampant in some areas.

Clovers are a very suitable companion partner, 'cuz they attract many beneficials. Clovers don't need a lot of sun which makes them work well with this.

The American Bittersweet is often confused with the Oriental Bittersweet. The Oriental Bittersweet is INVASIVE. Before removing or planting Bittersweet please look at this website ( ftp://ftp-fc.sc.egov.usda.gov/CT/invasives/asiatic_bittersweet.pdf ) to help you determine what Bittersweet you are removing or planting. American Bittersweet is native to America and is becoming endangered.

This is one of the most invasie plants there is in my area, they are terrible once it escapes it's planting area and is readily spred by birds. I would call it the mother of Boa Constrictors in the vine world. The seeds that make it appealing are the seeds of doom to native plants.

American bittersweet (Celastrus scandens ) is one of the most ornamental of our hardy northern vines. This deciduous, climbing woody vine is native to our area and is found growing in thickets, in stands of young trees, along fence rows and streams. It grows vigorously and can kill shrubs or small trees to which it becomes attached merely by tightly girdling stems and branches.
Bittersweet vines grow well in most soils, in full sun or shade, though adequate sun is important for fruit production. The only attention they generally need is a little pruning to keep the plants tidy or to limit their size. This may be done in late winter or early spring.

Bears pea sized fruits containing scarlet seeds but both a male and female plant are required. Fully hardy but only fruits well in a warm climate.
