Sounds like an interesting plant to grow and edible to make it even more enticing. Dr. Weil lists all sorts of benefits, so I am sure it has some beneficial properties. And it tastes good.
In the article you say if you are in zone 7b (which is my zone) or warmer, plant it in January. Do you mean in the ground or a pot inside and then replant in the ground in late spring? Is it similar in hardiness to cannas, gladiolus amaryllis and similar? I have been able to overwinter all of those with some mulching.
Thanks for the informative article.

You can plant it in the ground as long as it's not frozen. If you're not sure of the weather, you may want to plant in a pot and then move to the garden in Feb. or March. The reason for planting it in January is the plant dies back in about 10 months. So in fall, the top turns brown and it's the signal to dig up the rhizomes. if you can grow cannas, you can grow turmeric.
And thanks for reading it, Lance!

Thanks, sounds like a fun plant to try on my long list of gardening.
