Australian Tree Fern
They are an impressive evergreen tree fern, are thought to be one of the oldest plants in the world, and can make a true architectural statement in the garden, however they are very slow growing at only up to 30cm/year, their natural habit is to grow under tree canopies so therefore they require shade at all times, likewise the crown and roots must be kept moist at all times, to add to that they are not truly winter hardy in the UK so you will have to be prepared to give them some winter protection during the worst of the winter.
They are ideal in containers which means you can move them to shelter in the worst of the weather or alternately plunge them in the ground in their pots so achieving a natural look and then allowing you to move them if required.*
