Kress & Mood is a wild potential ornamental ginger naturally growing in the evergreen forest of North Eastern states of India was selected for the current study. The rhizomes were collected and stored at 15oC for 8 months during March to October. The sprouted rhizomes after chilling treatment were planted at regular interval and sprouted plants were transferred to greenhouse with controlled light during night hours using incandescent lamp to extend flower production from December to March.
