Hedychium chrysoleucum is a fairly recently named butterfly ginger with large showy white, often yellow cenrtred flowers. Another robust and jungly looking ginger with exotic foliage and stems reaching up to 1.75m in height.
As with all Hedychiums we grow, once the foliage has been frosted we recommend cutting the stems back to 30cm then mulching the base of the plant with 10-15cm of a good organic compost such as well-rotted farmyard manure. In really cold areas I would do this in addition to perhaps adding a layer of straw and also something like an up-turned terracotta pot to keep the winter wet and penetrating cold away from the dormant rhizomes.
As with all hardy or temperate gingers they all make wonderful container plants. If you prefer, this can be a good alternative way to cultivate them as they can easily be moved in winter to a frost free location such as a shed or garage to prevent the roots from freezing. As with most fast growing exotic herbaceous plants, regular feeding is essential for maximum growth and flowering. We recommend planting in rich, fertile composts either in the ground or container. In addition to this, regular liquid feeds of a fertiliser such as seaweed extract will reward you with lush growth and hopefully abundant flowers from mid-summer onwards.
