Alpinia caerula or native ginger is a popular choice in shady sheltered tropical gardens forming upright clumps of leafy canes.
The canes are pseudostems consisting of tightly rolled leaf bases.
The foliage is lush and glossy, the leaves large growing in rows on either side of the stem.
They flower in the second year, producing attractive clusters of unusual white/yellow tubular flowers with a distinctive circular two lobed lip.
Blue round capsules follows the flowers, the brittle skin contains white pulp and a black seed. The pulp is edible and according to Wikpaedia it is used by bushwalkers to moisten their mouths.
After fruiting the cane will die and needs to be cut to the base.
The clumps contain canes of various ages so will always look bushy and green.
