Re: Dahlia imperialis

<<Thanks to the very many of you who replied personally, to my query
about Dahlia imperialis.  From what I have learnt, it would seem that
I have a very good chance of getting it through the coming winter in
its arborescent form as opposed to having it die down to the rather
inadequate  tubers.  This bodes well for me winning my bet!>>
  David,
I think your real problem is going to be insufficant winter daylight. 
Here, in southern France, mine starts flowering in early November and they
go on for about a month.  I have seen them flowering in February, though! 
The tiniest cold wind will ruin the flowers.  They also need some wind
protection.  If you do get a frost they will usually start again from the
bottom and flower the same year.  I usually plant mine downhill from the
house so I don't have to stare into the sky to see the flowers<g>. 
Cuttings are easy - just get a bit of stalk and cut it so that there is a
knot at each end and push it in the ground/pot!
Hope this helps
  Eric
