they destroy neighbours' gardens I don't like them so much anymore.
Are there different kinds of ferns, some of which are suitable for
gardening and some of which are not?

Most ferns grow in clumps, and these won't spread too aggressively (and
are easily uprooted if they do).
A few ferns spread by creeping rootstocks. The most obvious of these is
bracken, which covers a lot of our hillsides and would be a nuisance in
the garden. The other creeping ones are more delicate and less
aggressive - at least the ones that grow wild in the UK.
There are also a number of ferns which are not native to the UK but
will
grow well here.
Most garden centres will have a stock of ferns.
I can't think of any ferns which grow on trees which would cause a
problem. But these ferns aren't so easy to find in a garden centre.

I thought that you could identify a fern by the spores on the leaves. *
If that is the case, bracken isn't a fern. * It just looks like one. *I
once lived in Wales but worked in Aston university, B'ham. * I was
asked if I could bring in some bracken that was wanted for some
research. * The arguement was that I had brought back some male fern
and not bracked, * Until I pointed out that there were no spores on the
leaves. * *Does it help???

Bracken is a fern. Those things on the backs of the "leaves" are
sporangia which are things that cover the places where the spores come
from. In some species, like Male Fern, these are very prominent and
easy to see. In others, they are only produced on certain fronds or
at certain times of year or on specialised parts of the plant.
Bracken does produce spores and in fact there have been health scares
regarding their possible carcinogenic properties.

In Britain, it is possible that Bracken does not produce sporangia and
spores very often but they do have them:
