Bittersweet is easily recognizable by its orange berries on vines which are often used in Thanksgiving and Christmas displays. However, there are two species of Bittersweet found in Indiana; American and Oriental. Guess which one is native and which is not!
They can often be found growing in the same places and look very similar until you start really looking them over and then you can tell them apart at a glance. There are a number of slight differences which add up to a different overall look.
The main thing is that the flowers/berries of the American grow in small bunches at the end of the twigs while they grow along the stem on the Oriental Bittersweet.
