Alpinia Zerumbet Variegata Plant Care
Size & Growth
Variegated ginger features upright clumps with fleshy, dense rhizomes, which resembles the culinary ginger.
This specimen plant with a rapid growth rate grows to about 10’ feet tall.
However, when grown as an annual in northern areas, it only grows about 3’ to 4’ feet tall.
Long arching stems grow from the rhizomes with several lance-shaped leaves.
As the name suggests, this plant has variegated foliage.
It produces green leaves with yellow stripes.
However, each leaf varies in its variegation amount – some are green with gold or creamy yellow strips, and others are yellow with green-colored streaks.
Flowering and Fragrance
The Variegated Ginger produces inflorescence of shell-like flowers.
These are often referred to as shell flowers since the buds bear a resemblance to sea shells.
However, it is important to note these pink flowers don’t blossom on the plants being stored for winter or grown as annuals since it only produces inflorescences on old growth.
This unique feature of this plant, making it different from other members of the ginger family, is the way the flower starts dropping instead of rising.
The flower color ranges from pink to white flowers and often turns bright red and yellow shades in the summer of the plant’s second year.
The typical bloom time of variegated ginger plants is the summer months.
The flowers have a slight fragrance. In rare cases, the flowers are followed by fruits.

The Shell Ginger enjoys growing in the full sun but needs part shade during the afternoon hours of harsh summers.
Even though it tolerates various light conditions, it is best to place the plant under a bright light.
Ideally, place the plant near a south-facing window when growing indoors where it receives part sun or filtered sun and is protected from the harsh rays of the midday sunshine.
The USDA zone of hardiness is from 8 to 10.
However, these plants might tolerate zone 7 when adequately protected during the winter season.
