It needs more moisture and very rich soil , big plants feed.

And Gunnera are part of the same family as rhubarb!

thank you all for your help, it is by a small pond but the soil is poor. From now on I shall make sure it gete plenty of feed

Ours took a while to establish itself by the pond now it is going great guns.

It also depends on which variety you have as well,
G magellanica, for instance only grows to about 4"
G tinctoria grows to about 6ft, while G manicata grows 6-10ft, so quite a difference. derekm

Agree we have G. magellanica, which is great and roves around and G. manicata which has not reached 10 foot yet!

Have you got it growing by a pond or lake? Gunneras are water margin plants so perhaps it's not growing in the right position.
