Not sure where I got the idea to try this except that the fresh Ginger (jengibre in Spanish) (hen-hebrey) I buy at Parisani has little "eyes" similar to potatoes. I had not read about the plant (annual or perennial), flowers or not, climate, soil, ornamental only or amount of sun.
Turns out it is a hardy plant that likes heat, humidity, water and fertilizer. I'll see how it does in the pot but it may end up in the garden because plants with rhizomes spread (put it where it can be controlled I read). Interesting to read about the history and origin of Ginger and how it got to the Americas. Haven't yet figured out the difference between common and ornamental. Ginger in Mexican cooking -- I heard in a certain Mole but nothing more. A continuing story I'm sure.
Tropical gingers, whether common or ornamental, require at least one year of undisturbed growth to bloom. Generally, the flower stems grow directly from a mature rhizome, although shell ginger's flowers grow directly from leaf stems. When growing new ginger plants from seeds or transplanted plantlets, they may require up to three years of growth before producing flowers. Planting ginger in a large, wide flowerpot and taking it indoors during winter gives the rhizome time to fully mature.

Think it's in a number of gardens around here
