Heliconia ×nickeriensis grows from 1.2-3 m in height. Heliconia species have one of two types of leaves; those with very short leaf stalks (petioles) that look like ginger leaves and those with long leaf stalks that look more like banana leaves.
The leaves of Heliconia ×nickeriensis are the second type with long petioles (22-60 cm) and leaves (40-82 cm in length) that have many conspicuous veins that run from the midvein out to the leaf margin. The inflorescences (flower clusters) of this species are erect and the boat shaped bracts that enclose the flowers are red at the base and yellow to orange at the tip. In one of the parents of this hybrid, Heliconia ×nickeriensis, the bracts are red with, once again, deep yellow apices. Individual Heliconia flowers are 3-parted with 3 green sepals, 3 yellow petals, 6 stamens and an ovary in 3 parts. Heliconia ×nickeriense has orange flowers that are 4-5.5 cm long. In all Heliconia species five of the stamens produce pollen and the sixth is sterile.
