Thewhite-flowered Tree Dahlia (imperialis) which I mentioned flowering
at Abbotsbury recently, has made the local (Weymouth) newspaper.
Today I had a phone call from the friend who took me to Abbotsbury, to
read me the item.
The Tree Dhlia originates from Mexico and has obviously been in the
gardens for a few years, but does not often flower, according to the
garden's curator, Stephen Griffiths.
I am still no wiser about the different colours you mentioned; Sacha's
gold and David Hill's pink. Has anyone any more info?
Season's greetings to all.

I must have missed something, somewhere. Our tree Dahlia is a single pink
when flowering, not gold. David Hill's is a lovely double pink and much
more interesting, IMO. Our guess is that ours is the species because (IIRC)
Philips & Rix show it and their pic is identical to what we have. But for a
white one, look at

and scroll down to the appropriate link.
Ours is much more like the one in this link:

Sacha, I was going by this post from Bob Hobden...........
Well mine doesn't flower, ever.
According to Ray at Hill House, where I obtained it, it needs to get
up to
the roof of his large greenhouse, about 18ft, before it flowers and
then it
has goldy coloured blooms I'm told.
You say the one you saw in flower had white flowers, and David Hill
said a
few months ago his has pink flowers, and both of them flower at a much
smaller size (half size) than the Hill House ones.
So, three varieties of one species? Hybrids? Anyone know?

Ours has been out in the garden for the last few years and survived
the
winters, but no chance of a flower, nice architectural plant though.
