The fragility of glass plays well against the strength and ‘rough outdoors’ feeling of a garden. Somehow it seems both slightly out of place and beautiful at the same time. Yet glass is actually quite robust – remember that we use it in external windows that protect our houses!
Glass sculpture for outdoor is not very common but there’s no reason you couldn’t use stained glass windows, blown glass or slumped glass.
Mirrors for outside use have to be specially made and well-sealed for that purpose. It’s not the glass itself that’s the problem; the silvering on the back of the mirror can discolour, making the mirror look blackened or stained.
You can use mirrors in several ways. The most common is to make a garden seem bigger than it really is by giving the impression that there’s more through a doorway or ‘window’, when it’s really the reflection of the existing garden. The mirror is often slightly angled so that you don’t see yourself in it from the main vantage point. Rather than more garden, you can angle it upwards as well so it reflects back skyscapes. I’ve often thought you could use low-down angled mirror to better enjoy those plants that like to hang their flowers downwards out of sight, like hellebores.
Another use is to reflect light into a dark, shady part of the garden by positioning the mirror to catch the sun.
A third way is to make the mirror a ‘picture on the wall’, where it reflects something if beauty that you would not normally see at that angle, such as the flowers turned to the sun, or some spectacular foliage.
The ultimate mirror text is to create illusions, as in this extraordinary garden designed by Rourke Hartwig at MIFGS 2012. Can you pick exactly where that waterfall is?

Although mirrors are truly great in the garden, one must be attuned to a couple facts that can create problems. Be considerate of where reflected sun may cause problems throughout the day.For the first day, let it become about every 1/2 hour, a commitment to check glare that is being thrown and where it goes. This can be a huge problem for neighbors, it can burn other plants, and even has been reported to distract low flying planes and emergency aircraft. Saddest of all is birds who think they too have an illusion of path or doorway to another area of garden. Although mirrors are very creative & pleasing for us, the poor things can get seriously hurt if not killed.
You raise some very interesting and important points there Lynn. Most garden mirrors I’ve seen are either relatively small and partially covered, or angled downward like you can see in the top picture, and so less likely to create the problems you mention of glare reflected at neighbours or upwards at planes, but it’s definitely something to keep in mind! Partly covering larger mirrors with foliage, or faux gates and window treatments creates a more convincing illusion of depth which would help prevent bird strike too.
Having checked into this further, I find that low flying planes, even as low as 1000ft, would see even a outdoor large mirror as nothing more than a small twinkling light on the ground. So no problems there.
Interesting ideas! We have used garden mirrors for some years now in our gardens in England. We have some more information you might find useful here….http://www.sandedge.com/acatalog/How_to_use_mirrors_in_the_garden.html
