Bittersweet
Then there is bittersweet, another wild vine that we gather in the fall. It covers fences and bushes as the clematis does, but instead of turning into fringe balls its small, creamy white flowers become bunches of berries.
The berries are yellow at first; when ripe they split open and curl back to show the brilliant red seeds inside that look like coral beads.
Gather the bittersweet while the berries are yellow, strip off the green leaves, and hang the vine up dry or put it in a large vase without water. Then the berries will open and last all winter.
