As you might recall, last summer I wrote a post "My Love Hate Relationship With Swedish Columnar Aspen", which is one of my top viewed postings. At any rate, I cited what I love about the trees and what I hated. The above photo is an example of what I hate about this otherwise beautiful tree. I found this little sucker growing between mine and my neighbour's houses. Left unchecked, this little guy would grow to the height of its parent plants in a few short years. See the parents below.
I exaggerate not. The Swedish Columnar Aspen grows on average 3-4 feet per year. This makes it a perfect specimen for use as a privacy screen. The biggest drawback is the suckering. Last year I found two in my lawn and one by my foundation at the back of the house. As seen above, our house is the one on the left. That's at least 10 feet away from the original tree! So much for being good as a foundation plant!
I am not the only one to have cited this drawback; see the comments on my post from last July.
Please, before you consider planting this tree, plan its location so it is far from foundations and water/sewer lines. They have been known to grow into water lines and clog them, repeatedly!
A good place for this tree is along the back of your property, away from foundations and water lines. Oh, and be prepared in the fall for repeated raking as they drop a lot of leaves and twigs, over a period of time.
The love part, in case you've forgotten there is something to love about the Swedish Columnar Aspen, is the sound of the leaves in the breeze. That is heavenly!
