Growing Some Weed(s) in My Village

It’s not officially illegal, but some question whether it should be. It can grow in between you and your partner, splitting you into camps, for it or against it. It can ruin a life or more; it can nearly take down an entire ecosystem.

Strangely, after cutting a ‘Mother Tree’ of European Buckthorn, a Great Blue Heron appeared in the forest to inspect our work. Near Wortley Village, Old South, London, Canada.

I’m talking about weed(s). The weed in question is European Buckthorn. A beautiful shrub in its own right and in its homeland in England, this plant that grows to the size of a small tree. It becomes loaded with dark blue berries that are favoured by many of our birds. E. Buckthorn has wreaked havoc on our natural areas and has quietly infiltrated Wortley Village (London, ON) via bird droppings. It often goes unnoticed and unidentified by homeowners. Before you know it, you’ve received a complimentary bird-planted Buckthorn for ‘free.’ The cost, however, of keeping this plant around in this neck of the woods or neighbourhood, is exorbitant. The City of London (Canada) alone has spent hundreds of thousands of dollars trying to remove it from our sensitive natural areas. From one little 2.5 acre plot at the corner of Rachel and Phyllis Streets, just south of Emery, the city and the Friends of the Coves Subwatershed removed several dozen tons (see pile in photo below) of this plant from the forest understory.

E. Buckthorn seedling I found in my garden this morning (5:30am) when I thought about this article. I pull them often and can almost always find one ‘one demand.’

By definition, E. Buckthorn is an invasive, non-native species It outs competes our native plants for space. So you might be wondering, are our native plants just wimpy and unable to hold their ground? No, this isn’t the case. What happened in this case is that E. Buckthorn was commonly planted in fencerows when it was first introduced in our area in the late 1800s to keep cattle in specified fields. While some large native trees were left, there were next to no natural areas kept fully intact. When grazing pastures and orchards were abandoned, E. Buckthorn were among the most common plants remaining, enabling birds to seed them across our landscape. As such, this plant has taken our over natural areas.

Note the large pile of cut European Buckthorn and the dark understory in the background – that’s all E. Buckthorn as well! The white ground herb in the foreground is Goutweed, resulting from an adjacent landowner dumping garden clippings on the edge of this natural area. 

Other detrimental non native species that we have commonly growing in the Wortley Village and that majorly impact our natural areas include Japanese Honeysuckle, Burning Bush, Goutweed (white plant in above photo), and Periwinkle. See this great guide (http://www.ontarioinvasiveplants.ca/resources/grow-me-instead/) put out by the Ontario Invasive Species Council called, “Grow Me Instead” to give you ideas for replacement native species. For starters, I’ve highlighted a native shrub that will nicely replace your E. Buckthorn, should you chose to move towards native plants; Pagoda Dogwood Cornus alternifolia. Its form is a beautiful multi-tiered stacked ‘pagoda’, while the flowers are whitish-green in spring and the berries are blue.

A friend and neighbour on my street inspired this article. He reminded me that a weed is really an unwanted plant, or one for which we haven’t yet found or identified a use. I find this wholeheartedly true. While I have reverence for E. Buckthorn, there is a proper place for it. It turns out it is sorely needed in England, where a species of butterfly (Brimestone Butterfly – below) is in decline, astonishingly and ironically because E. Buckthorn is vanishing from their countryside! Yes human induced landscape changes everywhere are having large ripple effects causing extinctions and inducing climate change. One sure fire way to mitigate these trends are to get ‘In the Zone’ (www.inthezonegardens.ca) and plant one or more native plants on your private landscape.
