dahlia imperialis

was given an dahlia imperialis [tree dahlia]it is a triffid it gets to about 6 metres, blooms in late autumn, has anyone grown one and how hardy is it, it can get cold in autumn do not want to lose it

 

thanks for reply will let you know it has grown so quick lovely leaf structure reminds me of rhus typhina

 

Brazil, When I was at Wisley garden a few weeks ago I think they had it bedded out in the borders.
Dont know but presume you treat it like any other Dhalia.

 

i work there i should walk round a bit more really cheers pete

 

Lucky so and so. What part do you work in?

 

plant centre and occasionally botany amazing place lunch in the gardens and all that it is a top job

 

Sounds good, especially this time of the year. Have a look up near the greenhouses in the tropical borders, where the bananas and cannas are, I think that where I saw the Dahalias.
