Growing Notes

Blyth's tall bearded iris introductions, from his New Zealand breeding program, are renowned worldwide for their exceptional form, innovative color breaks, and strong garden performance. 'Chinese Treasure' (1981) represents Blyth's early 1980s work, a period when he was producing some of the most exciting advances in TB breeding—particularly in the realm of plicatas, luminatas, and complex blends. New Zealand's maritime climate (cool summers, mild winters) selects for irises that perform well in less-than-ideal conditions, making Blyth's cultivars exceptionally adaptable. Tall bearded irises require a period of winter chill (vernalization) to bloom well. In warm climates (zones 9-10), they may need artificial chilling or should be grown as annuals. In optimal climates (zones 3-8), they are long-lived, low-maintenance perennials that increase steadily and provide decades of beauty with minimal care beyond division every 3-4 years.
