Here's an interesting use of a plant in the "wrong" place: this is a Cercis (canadensis) (pronounced sir-kiss, by the way) which is normally a small to medium sized tree. Someone rather foolishly planted it below the kitchen window (!) and the owner could barely see to do the washing up, so I was asked to remove or reduce it.
As the leaves are rather lovely, being a plump heart-shape with an elegant point, I thought I would try a form of coppicing, in order to encourage better foliage at eye level.
Accordingly, last spring, I cut all the main branches down to waist height, removed some of them altogether, and I brutally pruned off all the small branches, leaving just a short, drastically thinned-out skeleton of a shrub. It worked like a charm: last year we had a nice small bush, of lovely luxurious leaves, and washing up was once again easy to do.
Last autumn, I therefore pruned it again, removing all the new growth and taking it back to the skeleton.
This spring: just look! It has now produced flowers all over, even on the main trunk!
The owner was amazed, it had never flowered before: the previous gardener had only ever run a hedgetrimmer over it from time to time, when it got too dark to see in the kitchen.
So you can guess that I shall continue to prune this plant very hard indeed, in order to get a good show of flowers every spring, and to keep the leafy growth low enough to be enjoyable without obstructing the light.
It's still in the "wrong" place, but at least now we can enjoy it!
