I think this is Curcuma zedoaria

It may be C. zanthorrhiza or C. zedoaria. This can be confirmed only if the color of rhizome inside  and leaf nature are available. If the color of the rhizome is dark orange red and the leaf has dark purple patch along the midrib from base to top it would be C. zanthorrhiza. Whereas the rhizome is cream and a faint purple patch is seen along midrib it would be C. zedoaria. There are chances of C. caesia if the color of rhizome is dark blue inside.
Please check the details and send the photos again.

It is Curcuma caesia

If the plant is Curcuma caesia, the upper part of leaf should be hairy. Please check

kindly identify the Curcuma sp. I am attching the images of its flowers. Leaves have purple stripes and rhizomes are aromatic and when cut they turn bluish black.

attaching image with leaves. Attachments (1)

please check Curcuma aromatica

Thanks … but I have learnt through some papers that C. aromatica rhizome are yellow in colour when cut. But my plant has bluish black colour when cut. Curcuma caesia also looks same as seen in google images

could be, … is on the right track the flower does match what FOI has but this dark reddish middle streak in the  leaf is alo seen in the salled Kali Haldi Curcuma caesia,
we had it growing at the hort for a couple of years about 10 years ago. but the flowers would be different… sort of dark pinkish with magenta tint similar to what the wiki shows.
Ultimate confirmation would be to look at the rhizome!!! if possible.

just saw your response. yes you got it. you said your cut rhizome is bluish tinted…. voila. got the diagnosis. i donot know of many other rhizomes that can be blue. it is the kali haldi curcuma caesia.

I support …

it is Curcuma caesia or black turmeric.

Oh, thanks to …, I didn’t notice the the key character.
Blue and yellow rhizome distinguishes C. aromatica and caesia
