Hello
As a Frenchman leaving in California , I was puzzle by your French alternative , sadly I found none .
My tree dahlia imperialis reach 20 feet almost every years , I leave in San Francisco bay area where it does not get really warm . , not cold either some white frost in the winter .
my only problem has been wind damage , when the wind break them I le them down until it is no longer cold to cause damage to the plant then I do trim them where the break occur , they grow back with a much stronger stalk .
I am looking for the double white tree dahlia seed , as it is much easier to handle . anyone have them please drop me a line .
By the way I did plant them among my giant bamboo , the neighbors are wondering where did I buy flowering bamboo .. best Joel

Answer:
Hi Joel, The double white tree dahlia is a generally sterile mutation raised in cultivation, thus there is no seed available. It strikes very easily from cuttings, so I suggest that you check with local garden clubs and Google. The French alternative on our site is gardening ideas from Jackie French. Don
