Caring For An Zingiber Zerumbet

Size & Growth

With a clumping growth habit, Zingiber Zerumbet usually grows about 4’ feet tall, however, in some cases, it is found to grow up to 6′ to 7’ feet tall.

It’s reed-like, erect stems rise up to 4’ feet and are clumped by sheaths of 8” inches long, narrow leaves. 

The inflorescence grows 2” to 4” inches in length.

Shampoo Ginger Flower and Fragrance

Aromaticum is a broad-leaved plant that produces showy blooms on flower stalks from August to September. 

In spring, 9 to 12 blade-like green leaves appear on the underground stem. 

By mid to late summer, the thick ginger shampoo plant rhizomes produce flower spikes each topped with a globular, brightly-colored inflorescence.

The inflorescence resembles a pinecone and is initially wrapped by green, waxy bracts, which turn a vibrant shade of red upon reaching maturity. 

The red pine cones have a fresh, aromatic, ginger-like scent.

The pinecone-shaped inflorescence produces tiny tri-petaled flowers in hues of yellow and is full of fresh-smelling, bitter-tasting, creamy white sap.

Shampoo Plant Light & Temperature

Bitter ginger is winter hardy to the USDA hardiness zones 8 through 10. 

The awapuhi plant prefers tropical or subtropical climates, but also grow in mild climates on the mainland. 

In colder climates, pinecone ginger plant is grown indoors. When growing outdoors in Central Florida the pinecone ginger begins to dieback as the weather changes.

The ideal temperature for these exotic plants is 32° degrees Fahrenheit (0° C) or higher. 

These perennials enjoy full sun to part shade.

Watering and Feeding

Shampoo ginger should be seasonally waterlogged. 

Water them with free-draining soils during the warmer months and keep them dry during the dormant winter months.

Similarly, fertilize shampoo ginger plants with an all-purpose fertilizer during summer only. 

Supply phosphorus-rich fertilizer by the end of the growing season to ensure healthy and well-grown rhizomes.

Soil & Transplanting

Pine cone ginger thrives in filtered shade and rich soil. 

It prefers soil with a neutral pH and a light to medium texture. 

In summer, provide the plant with consistently moist soils and keep the soil dry during winters since the plant goes dormant and requires less moisture.

While the shampoo plant shows great tolerance for poor sandy soil, hard soils need to be adjusted by adding gypsum before planting the plant.

Wild ginger is cultivated by seeds and rhizome extracts. 

Transplant the plant by harvesting new shampoo ginger rhizomes 10-12 months after planting, preferably in late winter or early spring.

Grooming and Maintenance

Shampoo ginger lily is a forgiving and fast-growing perennial which can spread across a garden within years under ideal conditions.

In USDA Zone 8, these plants survive winter when mulch is added to the soil and the roots and rhizomes are protected from freezing. 

However, in regions located in the north of Zone 8 up to Zone 10, the rhizomes should be picked up and overwintered indoors.

Also, potted plants should be kept indoors, away from the frost, when temperatures fall below 55° degrees Fahrenheit (13° C).

Snip the leaves which die to the ground after the first frost. 

Keep an eye out for pests and, if infested, spray with a strong water jet and apply plant-based horticulture oil on the leaves. 

Do not apply oils when the climate is hot and humid.

Zingiber Zerumbet Propagation

While Zingiber zerumbet grows via seeds and roots bought from the store, the most preferred method of propagation is via rhizomes.

  • Wear gloves and use a sharp knife to cut the rhizomes in pieces. 
  • Each piece should consist of several buds. 
  • Keep the pieces for a few days until the cuts are dry.
  • Next, soak the pieces of rhizomes overnight in a container filled with warm water. 
  • Take equal parts of potting soil and compost in a 5-gallon container and mix the ingredients until a rich, moist mixture is obtained. 
  • Fill the pot with this mixture and plant a couple of pieces half-inch deep in the soil with the buds facing upwards.
  • Keep the plant indoors in a warm, sheltered place with filtered light. 
  • In colder regions, place it under full sun. 
  • Water the plant whenever the upper surface of the soil feels dry to touch. 
  • Supply organic fertilizer twice a week until the rhizomes have sprouted.
