Believe it or not I have had success growing this ginger in SE PA. I live in the Philly metro area. The plants are along the south side foundation. For 6 years now I have left them to overwinter. By late spring they send up large leafy stocks and by late September as the weather turns colder they flower. I have read they are native to the foothills of the Himalayas. They are great as cut flowers and very fragrant.

This is a WONDERFUL container plant! No need to worry about it becoming invasive that way. The fragrance from the long lasting flowers is intoxicating. Hummingbirds love them!
The rizhomes can take a while to produce shoots, but once they do, they grow steadily. I'll add a couple of photos here to show you what great foliage they have also. They'd be great in a long deep planter box to make a short living screen.

This plant has been identified on the ISSG Global List of Invasive Plants
Responsible gardeners may wish to consider their local conditions prior to introducing or trading this plant.
Hedychium gardnerianum (herb)
This showy ornamental ginger grows over a metre tall in wet climates and grows from sea level to an altitude of 1,700 metres. It displaces native plants, forms vast, dense colonies and chokes the understory vegetation. It may also block stream edges, altering water flow. It is dispersed by birds over short distances and by man over long distances (as garden waste or via the horticultural industry). Even small root fragments will resprout, making it a difficult invasive to control.

Kahili ginger grows almost as an invasive plant in some areas of this island. At the Volcanoes National Park on the Big Island, they are trying to eradicate it as much as possible as it takes over the areas where some native plants are growing.
I think they are beautiful and used to have some growing in the place where we were previously living. Very fragrant and beautiful!
The name kahili (kah -he -lee) is named for the old yellow feather standards carried by attendants of the old Hawaiian Ali'i (royalty) since it resembles them in shape.
Tall perennial which produces rhizomes, long lance shaped leaves which can be glossy green or a greyish colour.
The flowers and scented and held in a dense cylinder manner, pale to bright yellow flowers have long red stamens which are very visible.
Frost tender but can be grown out side in zones 8 and above with a deep winter mulch.
