Japanese Honeysuckle is another of those nasty invasive honeysuckles.  In Indiana, it’s found mostly in the south side of the state.  I’ve never seen it in northeast Indiana.  Those in the know state that it is quite difficult to control once it forms a dense layer of honeysuckle vegetation along woodland edges.  It is declared a noxious weed in many states and is banned outright in New Hampshire.

On the other hand, it is possible to buy it for landscaping purposes because it is a very effective ground cover.  Too bad the right hand doesn’t know what the left hand is doing in this case.

It’s a viney honeysuckle.  It twines all over everything so it can look like a shrub, but close inspection shows it to be a vine.  Its flowers start out white, then change to yellow.  The flowers have one four-lobed petal above and one skinny petal below.  This is quite distinctive for the honeysuckles.
