People unfamiliar with the conditions should look at the Climate FAQ

Janet might be able to grow Chinese gooseberry (Kiwi fruit), but
I suspect not, and doubt very much that it would fruit. It does
It might in a warm year. Not that they are worth the effort.
in the south of the UK, and in a warm position (e.g. on a suitable
wall). Similarly, avocado might grow on the south coast or even
in the smokes (er, Middlesex), but the same applies.
Unless the OP plants their 12 inch avo, they will never know if the
plant will grow and fruit or if it will not.
The least bad chance is somewhere more or less frost free on the SW
coast but the summer will never be warm enough to get any fruit even if
the tree just about manages to stay alive (which I doubt).
A lot of garden advice is "knowledge" that is simply recycled endlessly
without that "knowledge" ever being put to the test.
I have played around growing things unsuited to UK conditions outside. I
have cacti growing outdoors carefully chosen and large enough to survive
but growing is all that can be said for them they take bad frost damage
and are unsightly. A sheet of glass or plastic to keep the rain off and
very sharp drainage on a raised bed helps.
In a bad year I lose them and have lost an expensive tree fern I reckon
on a single night where I failed to anticipate a late frost and cover it.
I planted my mandarin tree when I went to visit a woman who had these 2
huge mandarin trees on either side of her front door. I said to her and
I KNEW they wouldn't grow where she lived. Her response is that every
single gardener who visited her told her the exact same thing and the
mandarins just kept on ignoring such advice.
I can grow citrus in pots outdoors in summer and under glass in winter.
They would be very unhappy planted outside in a cold foggy air and wet
waterlogged ground.
There are numerous techniques that can be used to get plants to grow
where they supposedly won't. Just one example I've seen is where grapes
were grown in 6 ft deep slit trenches with corrugated clear roofing
sheets on top of them. The grapes were growing well and had fruit and
the owner of those grapes had been told that he couldn't grow grapes in
his climate so he set out to prove he could do it. His worst problem
was kangaroos jumping on the roofing and falling through.
Grapes are easy under glass even in the UK. There are working vineyards
for winemaking now as far north as 54 degrees. Edith Sitwells Renishaw
Hall used to be the most northerly until comparatively recently.

The record is (probably) still held by Mount Pleasant wines in Camforth
at 54.1N

Since the OP asked for any advice, mine is to plant their 12 inch plant.
It may grow. It may even fruit. They won't know until they test it out.
It will almost certainly die in the first winter. But no great loss. It
will only ever be a leggy stick with a few leaves on the end. I have
grown one in Frodsham Cheshire and planted it out with predictable
results. Nectarine with shelter was almost successful by comparison.
I have also grown under glass (heated greenhouse) and lost a jacaranda
tree and various other exotics. Some things are not as tender as people
would have you believe but most things that are frost hardy in a dry
cold continental winter are very difficult in a dismal wet UK one.
