Hyn That ginger looks fantastic. Its so weird, mine was growing and failed again. Not sure whats wrong. It'll sprout roots, send up a shoot and then die. Strange.guess its too late to re-start for the ... 4th time. But on the other hand, I'm doing super with the turmeric and its my first time. Here's 2 sets started, large ones are 6 weeks and smaller ones are 4 weeks. When I switched pots I already saw the roots getting fat, but I do want to leave one pot designated to get flowers cause they look so beautiful.

I have several curcuma and globba gingers in pots due to armadillas digging stuff up. They like to eat my ginger bulbs. Anyhow, rihjt before our first freeze, I let the pots totally dry out and when the foliage dries up I clip it off and put the pots in a shed over the winter. It stays above freezing in the shed although Curcuma and Globbas can take some freezing temps. In late April, I take the pots out of the shed and set them in semi shade and water them. Pretty soon they start leafing out. You must just water them a little until they leaf out. You dont want the pots soggy or they will rot. Been doing it this way for about 5 years now :)

I had one call siam at my last house when I moved in. couldn't figure out what it was for the longest time. A co-worker of my wife from India told me what it was.had a really neat flower that was white with purple tips.

That doesn't look like edible ginger. That looks like pine cone ginger (shampoo ginger or bitter ginger). Edible ginger like you find in the grocery store has very long, thin leaves and very small, white flowers that aren't very showy. Let the flowers grow. They're really beautiful when they turn red, plus, you can shampoo your hair with them. I've done that a couple of times when I was out of shampoo. Works great and makes your hair really soft. You can also eat the roots of these, but they don't taste like the ginger root you buy in the store. You have to dry them and pound them into powder to use the roots, and it's not used much for cooking, mostly medicianlly . If you want some kitchen ginger (Zingiber officinale) just buy a couple of pieces and plant it just barely covered (about 1/2 inch of soil), and you should have some soon. You can also grow it in pots. Zingiber zerumbet (shampoo ginger) Zingiber officinale (kitchen ginger)
