I love this time of year because although you can plant for autumn colour, until it actually happens, you never know how it will look and whether the leaves will stay on the trees long enough to make it spectacular. My oak is putting on a real show this year, as are the japanese maples. Cherries were lovely but didn't keep their leaves for long enough. Its going to be a mainly gold year for the liquidambar and parrotia (some years they go quite red) and the mimosa is starting to bloom very early, normally it isn't out until January. My favourite time of year.
