Colocasia esculenta 'Mammoth'

In our opinion the best large leaved Colocasia for growing outdoors in the UK.  Has outperformed others such as Jack's Giant for us over many years.   Once in active growth, keep feeding and watering regularly up to autumn to achieve the largest leaves.  Either lift for the winter months, or mulch heavily to protect from the worst of the winter months.  Needs a well draining spot if left in place for the colder months. 

Quite Hardy.
