Common Name: Mistletoe.

Illinois Distribution: Occasionally in the southern one-sixth of the state, but extending along the Wabash River to Clark County.
Mistletoe is a remarkable plant in the Illinois flora. Although possessing chlorophyll in its leaves that enables it to manufacture food, it also obtains nutrients from the host species it parasitizes. The hosts in southern Illinois for the mistletoe include American elm and sweet gum. Excessive numbers of mistletoe plants on a single host may ultimately result in the death of the host.
Mistletoe seeds are dissiminated by birds that attempt to eat the berries. The sticky berries adhere to the bird's beak. In order to rid itself of the berry, the bird will rub its beak back and forth on the branch of a tree, finally transferring the berry from beak to branch.
Because of its popularity at Christmastime as a traditional decoration, mistletoe is sought after and is becoming less common in Illinois.
The flowers bloom during September and October.
