I'm afraid that name has turned into a bit of a catch-all, so it's
difficult to say what cultivar it is exactly. Much of the stock
breeds fairly true from seed, so that individuals (even grafted)
may not be true clones of the cultivar named in 1910, and
stock general available has become a grex.
All of this matters of course not at all to the enjoyment of
the plant! Palmatum is so variable that there are thousands
of unnamed but desirable expressions around.

However, last year it failed for the second autumn to turn bright
orange / red because it didn't even went all red but was over 80% I'd
say with green leaves. This year, and I'm not too surprised because of
the long warm weather we've had, it gave some fruits for the first
time. Now, I wondered if you knew why it's now not going red as it
should?
There are two possibilities. It may need more sun. Many of
the red cultivars go green from insufficient light. The second
is that it was grown from seed or is a grex, some of which
turn dark green in fall. I'd consider the first more likely,
personally.

Another possibility is that Autumn was very weird this year . Certainly in
this part of Yorkshire the Autumn colours did not develop as well as normal
on both Acers and several other trees. The Acers started on the normal cycle
and then the leaves just flopped and hung around for ages in loose
colourless clumps.
Normally they strut their stuff and fall in one big whoosh within a day or
two of the first frost.
