Grow in a sheltered but sunny spot and you can expect these enormous plants to grow upto three metres high. They prefer these conditions with moist well draining soil. Even still, with mild winters and mulching they can be left in the ground with some success over winter.
The appearence is quite unlike your usualy dahlia with single drooping pink flowers and foliage on bamboo like stems.
