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.
