In my garden I have a couple of Ferns in pots, like this:
But I also have some others (their offspring) in one of the beds, where they serve to screen the rather austere pot in which I have some climbing beans growing:
They are small at present, but they will get a lot bigger.
They remind me of the curly bit at the top of a Double Bass (called a "scroll")!
Ferns are good plants to consider if you have any awkward corners in your garden where little else will grow, because many of them will thrive in low light conditions. Some will tolerate very dry shade and some will tolerate very wet conditions. However, don't assume that all ferns are the same in this respect, and do some research before you buy any. The one I bought last year is Dryoperis Erythrosora, which is one that will do OK in dry conditions. Its young foliage is a lovely bronze colour, gradually turning to green as it matures.
