Elaeagnus umbellata (Autumn Olive)

Again I was disappointed to discover that one of our trees is considered to be invasive on this continent. This tree was growing on the east side of our house in an area where I had given up mowing during one of the first years that we lived here. I was using a reel mower (the kind with no motor), and this area stayed wet well into the spring, making more unnecessary work than I wanted to do. So, partly out of curiosity, I just left that area to whatever wanted to grow. After a decade, the primary vegetation besides grass, goldenrod, and assorted weeds, was naturally buckthorn, honeysuckle, and a handful of small ash trees. There were also a few crabapple, cherry, and sumac trees. But there was one very bent-over tree with a bunch of suckers that I thought was some kind of willow, but had not taken the time to identify. Yesterday I noticed a bunch of yellow trumpet-shaped flowers on it and eventually identified it, first as Autumn Olive (Elaeagnus umbellata), then as Russian Olive (Elaeagnus angustifolia). Then after vacillating for a while, I settled back on Autumn Olive. It really doesn't matter which, because both are listed as invasive, so I plan to cut it down either way. I had considered letting it grow until it bore fruit, so that I could taste it - it's supposedly very good for you. But I'm heading out to cut it down now to make room for more desirable tenants.
