Mile-a-minute vine, also known as devil’s tail and tearthumb, is an herbaceous annual vine in the buckwheat family. If you’ve ever encountered it you will know where the name tearthumb comes from. It is native to Asia but has become naturalized throughout the area and is a serious pest. Think of bindeed on steroids and with seriously barbed stems but without interesting flowers. It does have interesting fruit, I have to admit. These little berries are less that 5mm across but they are such a clear, beautiful blue, I cannot help but enjoy them. That’s not to say I would ever consider growing this for the ornamental value of the berries, of course. But they are still pretty.

Cathy and I went for a walk near Lake Frank today, parking on Bauer Drive and walking in through a break in the houses (there’s a lot that’s not privately owned) and then along the road that leads, within the park, the the parking area. That road and parking area are not in use and haven’t been for many years although I’m not entirely sure why. It was a pleasant walk and we enjoyed the late autumn colors reflected in the lake as well as the oriental bittersweet (Celastrus orbiculatus) in a few places. I don’t recommend growing this, but I have to admit it’s pretty.
This is one of the more prevalent weed shrubs in our area. The Amur honeysuckle (Lonicera maackii) is an east Asian native that has firmly established itself as noxious weed in the eastern half of North America. It’s got the sweet, tubular flowers typical to honeysuckles, starting out white and aging to yellow. They are followed in the fall (right about now, obviously) by bright red, juicy berries. Although they are inedible to humans, birds eat them and spread the seeds far and wide. They were once planted as an ornamental and you can see why. However, they are no longer recommended, because of their invasive nature.
There are places where English ivy (Hedera helix) looks really nice. It’s also a very good ground cover for many situations. Nevertheless, I’m not a huge fan. In a city, where it can perhaps be contained reasonably well by paving, etc., it’s suitable. In the suburbs and rural areas it can really be an annoyance. This ivy is growing up a tree near my office and you can see how it grips its host. It will grow up into the tallest trees and eventually strangle them. It also covers the ground so completely that in often chokes out less aggressive plants (and there are only a few more aggressive). We’ve done our best to eliminate it from our yard and with a small patch that seems to reappear occasionally, we’ve succeeded. But we remain on DEFCON 3 or higher.
