This cross between the Asian and American species has produced plants that grow vigorously, producing a large number of new buds each season. I have only had the stock for two months but the rhizomes have doubled in size. In a pot it needs free draining compost as it does not like anaerobic conditions. Planted in the garden it should spread rapidly. It needs a damp but not waterlogged position. From experience over the years with E gigantea I have always found it did better in places where the plant got a reasonable amount of sun. however, as the influence of the Serpentine night can be seen in the spring with purple on the growth. This colouration is lost when the plants develop and are in the sun.
