tree dahlias
The Night Time Gardener (Tue, 12 Mar 2019 16:12:08 PDT)

There is an Dahlia imperialis at the JC Raulston arboretum in Rahleigh, NC
zone 7b. It blooms some years in November if the frost stays off long
enough. I was told it has struggled to come back after harsh winters but
always does and they do nothing extra ordinary to protect it. For what it's
worth.

Hi Ken
I’m in Washington and have had success with my tree dahlias but not
blooming I picked up plants from Tony when I lived in MD and have been able
to keep them alive for several years, the last two years have been in NC’s
heat. But not any flowers yet. I remember seeing them easily 3 meters when
I was at university in Melbourne when they do get 35 C heat.
I think they are very fascinating and look forward to a second story
window with flowers blooming in early Nov.
all the best

Wow. Coincidentally, my wife and I just returned from a garden tour in
beautiful New Zealand. I've sent a note to Dr. Hammett, but do you think
the hybrid tree dahlias would do well here in hot and muggy North

Carolina

(USDA Zone 7a) where the temperature very seldom goes below 0 degrees
Fahrenheit? I am also interested in any other plants he might have, but

I

don't know where to start. I would appreciate any advice you can give.

Thanks,

I am growing hybrid tree dahlias from Dr Keith Hammett in New Zealand.

He

is sold out for this year, though.
