The Giant Rhubarb plant.
Supplied in a 9cm pot
This is a monster, jungle plant that can produce leaves that create the look of prehistoric jungle. At best the plant will put up leaves that are 2 meters across and on stems of 1.8 meters. They need a rich, constantly moist, almost boggy ground to do this. If planted in more modest conditions this water loving plant will grow proportionately smaller.
The pictures of the specimen plants were taken at Trebah gardens in Cornwall and show what is possible.
Protect in winter by simply cutting back the leaves and turning them upside down over the growing points of the rhizome.
Moist soil/boggy conditions
