More Information
Gingers & Heliconias are generally plants for the tropics and subtropics. For borderline climates like Sydney, consult a specialist ginger nursery to find out which varieties are most cold tolerant.
Although they're not woody plants, some types can reach heights of several metres. Not all grow to these proportions, however, with other varieties reaching only 50 cm or less.
Most cultivated members of this group are "exotic" in terms of both looks and origin, but Australia does have some native gingers. Alpinia coerulea is widely available and a popular choice for rainforest gardens. Curcuma australasica is another Australian native becoming popular with ginger collectors.

Ginger and heliconia aphids may or may not be banana risk
The banana aphid, Pentalonia nigronervosa is vector of banana bunchy top virus (BBTV). DNA analysis of aphids collected from several countries including Australia, showed that aphids from banana are genetically different from apparently similar aphids from heliconia and ginger plants. This has implications for BBTV research as some of the previous work on the aphid may have involved the wrong species (Pentalonia caladii). If it is found that the ginger and heliconia aphids can't transmit the virus, they can be ruled out as a treat to bananas.

Three species of ornamental ginger declared weeds in Queensland
Yellow ginger (Hedychium flavescens) is now a Class 1 weed
White ginger (Hedychium coronarium) is now a Class 3 weed
Kahili ginger (Hedychium gardnerianum) is now a Class 3 weed
All are now illegal to sell or trade in Qld, while landowners who have yellow ginger on their properties must eradicate it. More information on declared weeds in Qld, the classification system and your obligations at the Biosecurity Queensland website. (November 2010)
