Hedychium ‘Tresco Hybrid; is, as its name suggests originates from the Abbey Gardens in the Scillion Island of Tresco where it grows abundantly producing stout stems up to 1.2cm high which in late summer are topped with spikes of creamy flowers adorned with pink-ish stamens. If this is not enough, the large flowers are heavily perfumed. Possibly a hybrid of Hedychium gardnerianum and coronarium ‘Tresco Hybrid’ is a strong grower and best of all for us, it flowers earlier than both its possible parents. In summary, an easy to grow Hedychium which should be perfectly hardy in southern England and elsewhere in the UK given our suggested protection
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.
