Multiflora Rose, Rosa multiflora, is scattered around the property, mostly in the woodland edges. These roses can be identified by their frilly stipules (leafy appendages at the base of the petioles), but now are very obvious by the clusters of fragrant, small white flowers. I had hoped that I had some native roses out in the field, but so far it looks like they are all Multifloras.
|Left to its own Multiflora Rose will send stems high into a tree.|
It turns out that a couple of small trees that I thought were Pin Cherries are actually Autumn Olives, Elaeagnus umbellata. My mistake was made clear at the beginning of May when these plants were coming into full bloom. I was drawn to the wonderful sweet scent. When I saw the flowers I realized that what I had was definitely not a cherry of any kind.
|These two Autumn Olives are nicely situated on either side of a path. |
I'll cut them down soon and replace with something native,
maybe Winterberry Holly and Tupelo
|These fragrant tubular flowers |
were very popular with the bees.
I decided to let these finish flowering before cutting them back to a stump and then treating the fresh cuts with Round-Up concentrate. This seems to be a pretty general method for killing undesired shrubby vegetation. I did this to a very large Euonymus alatus in mid-March and I have seen very little if any regrowth so far this season.
When we first moved in last fall I noticed a lot of honeysuckle vines growing everywhere. I had hoped that they were the native Coral Honeysuckle, Lonicera sempervirens. There were no berries present (Japanese Honeysuckle has black berries, L. sempervirens has red berries) so I couldn't tell by that. Also a cross section of the stem appeared to solid, not hollow, so I assumed it wasn't Japanese Honeysuckle. Now that they are coming into bloom with their sweet-smelling white flowers, I see that I have a lot of the invasive honeysuckle. A check of the stem shows that these are in fact hollow, so looking at the cross-section of the stem may not be a great late season indicator for this species.
|Japanese Honeysuckle flowers start off white, then turn yellow after a couple of days.|
I'm not sure what approach to take on all the trailing stems on the ground. Pulling and late season herbicide applications can be effective (as long as the leaves are still photosynthesizing). In the interim I have been cutting the stems of the vines up in the trees to minimize seed production.
|Note the white center vein on the leaf.|
As an annual it can be controlled if you can keep it from going to seed. Cutting it back when it begins to flower in late summer can keep it from successfully setting seed. Cutting it back earlier may stimulate earlier flowering. For plants in the woods I will go after them with the weed wackier in August. This grass has a weak root system and is easily pulled up, but there is just so much!
This is a very leafy grass and is soft to the touch. The shiny mid-rib is a feature that sets it apart from other grasses
|This is a recently opened-up area where the stilt grass is going to town. |
It is joined by some garlic mustard and bittersweet.
The near-by poison ivy is slowing my progress here.
|Note the triangular leaves of Mile-a-minute vine. |
There are nasty thorns forming on all parts of this vine.
Mile-a-Minute Vine is a very fast growing invasive. Once I noticed it I took some time out from writing this post to pull it out right away. It is really important to do this before its many thorns begin to harden. In my enthusiasm I accidentally pulled up a new Redbud tree, because its heart-shaped leaves looked similar to the triangular leaves of Mile-a-minute.
