I'm guessing it can be grown from the rhizomes I have, just like ginger. I almost certainly won't find the seeds here. This site seems helpful.
Yes, it should be grown from the rhizome - I don't think I've ever seen it planted from seed. Take a look at the rhizomes you have and see if any have any growing points - you can cut on either side of it (or just plant the whole section) and plant it and it will grow a shoot, and the rhizome will then start expanding laterally. I don't know if it would be too painfully slow to watch on your vpn, but YouTube has a ridiculous amount of "grow your own turmeric/galangal/ginger" videos....
