To further add to George K's wonderment and confusion this plant is probably known to some as Winter Creeper. Although highly invasive it does have its uses.

In our case, our drive gives way to a steep drop before the back and side yards start. We stabilized this with heavy rock and then to keep that from rolling into the yard we planted Winter Creeper which has grown to a nice two foot shrub like appearance and being Evergreen remains attractive year round. The fruits are similar to those in the picture but a little more on the orange side.

The nps.gov site describes is as follows:

Euonymus fortunei (Turkz.) Hand.-Maz.
Bittersweet family (Celastraceae)

Origin: China, Japan, Korea

Background
Winter creeper, or creeping euonymus, is an evergreen perennial vine that was introduced as an ornamental groundcover.

Please note that any queries re: the abbreviations above (Turkz. Hand.-Maz.) should be forwarded to Billy Joe Fudge.
