Red ginger is a clump forming ginger with red spikes for flowers. Very showy against the shiny green leaves. Flowers get bigger with time. They are great cut and are famous in tropical flower arrangements.

Tahitian ginger (Alpinia purpurata).

'Tahitian Ginger' looks similar to the common red ginger when it begins to flower, but the inflorescence continues to branch, forming a gigantic ball of flowers.
