Susan, I'm not in the UK, I'm on the east coast in Maryland, but I'll be
glad to share my experience with this plant.

The short story is that it's easy and quick from seed, grows like a weed up
to about eight feet the first year - and does not bloom. It does not bloom
because we have frosts before the flowers develop.

If I grew short-day-length chrysanthemums under tents, I might be tempted to
try this one again. Photos I've seen suggest that the flowers look like
those of pink Cosmos bipinnatus. 

For those of you who don't know it, this is not simply another Dahlia. It's
a very distinctive foliage plant, with huge compound leaves held at a
characteristic angle. It's worth having simply as a foliage plant. The
foliage reminds me a bit of that of Melia azedarach.

Montgomery County, Maryland, USA, USDA zone 7, where two or three Crocus
kotschyanus and C. speciosus are so far all I have to show in the way of
autumn crocus.
