Awapuhi, or “shampoo ginger,” is a tropical perennial (Zingiber zerumbet) prized for its ornamental appeal and traditional uses. Its unique cone-like inflorescence yields a fragrant, conditioning liquid. This ginger species is recognizable by its tall, reed-like stems and distinct pinecone-shaped flower heads that mature from green to a vibrant red color. Acquiring this specific plant requires attention to identification, sourcing, and initial planting procedures.
Identifying the Correct Awapuhi
The term “ginger” applies to many species, so it is important to confirm the correct plant is Zingiber zerumbet before purchasing. This species is often called pinecone ginger or shampoo ginger. The plant’s pseudostems, formed by tightly overlapping leaf sheaths, can reach heights of four to seven feet.
A distinguishing characteristic is its deciduous nature; the leafy growth dies back completely in the fall and winter, leaving only the perennial rhizomes underground. The flower heads emerge separately from the leafy stems, growing directly from the ground on shorter stalks in mid-to-late summer. These inflorescences are initially green, waxy, and cone-shaped, gradually filling with the ginger-scented liquid and turning bright crimson as they mature.
When acquiring live plant material, you must be aware of shipping regulations designed to prevent the spread of pests and diseases. The United States Department of Agriculture (USDA) and state agricultural departments enforce specific quarantine laws, particularly for movement across state lines. Shipments of live plants or rhizomes may require specific labeling, inspection, or phytosanitary certificates. Buyers should verify that the seller is compliant with all interstate shipping rules to avoid seized shipments and potential fines.
Retail and Online Acquisition Methods
The most direct way to purchase Awapuhi is through specialty tropical nurseries, which often carry certified, high-quality rhizomes or established potted plants. These dedicated growers are typically the most knowledgeable about the specific plant’s needs and are more likely to comply with necessary shipping regulations. They frequently offer the plant as a dormant rhizome.
Online marketplaces, including dedicated plant websites, Etsy, and Amazon, are common sources for purchasing Zingiber zerumbet rhizomes. Buying dormant rhizomes is often preferred for shipping, especially during cooler months, as they are less susceptible to cold damage and transplant shock than a fully leafed plant. When buying rhizomes, look for listings that specify the scientific name and include clear photos of the knobbly, pale yellow root with visible growth points, or “eyes.”
Purchasing an established, potted plant is another option, though this typically carries higher shipping costs due to the increased weight and size. Potted plants offer the advantage of an established root system, which can reduce the time until the first flowers appear, often within one or two years of planting. General garden centers or big box stores may carry the plant regionally, but availability is less consistent, and staff may not confirm the exact species or the plant’s dormancy cycle.
Establishing Awapuhi After Purchase
The first steps after acquiring the plant material are crucial for successful establishment, whether you receive a dormant rhizome or a potted plant. If you purchased rhizomes, they should be stored in a cool, dry place if you cannot plant them immediately, and they should be checked for viable growth points. Prior to planting, allow any cut surfaces on the rhizome to dry or “scab over” for a few days before soaking them in lukewarm water overnight.
Planting Rhizomes and Potted Plants
Awapuhi thrives in well-draining soil that is rich in organic matter, such as a mix of loamy soil and compost. If planting rhizomes, lay them horizontally about two inches deep with the growth buds facing upward. Space them 12 to 18 inches apart to allow for lateral spread. For potted plants, select a container with good drainage and plant the root ball at the same depth it was in the nursery pot.
Location and Watering
The initial location should provide partial shade or bright, filtered sunlight, as direct, intense sun can scorch the leaves. Immediately after planting or transplanting, water the soil thoroughly to settle it around the roots and eliminate air pockets. During the growing season, the soil must be kept consistently moist, but not waterlogged, to encourage strong growth and prevent the rhizomes from rotting.
