Shampoo Ginger
When we had a bathroom renovated, our contract manager became our friend. Hugo was a great gardener and loved the variety we had planted in our backyard. We shared cuttings and rootings, and he introduced us to Shampoo Ginger, also known as Zingiber zerumbet, pine cone ginger, and pine cone lily.
Our first winter, we thought we had lost the plant entirely to the cold, even though we had wrapped and sheltered it. Late in summer, we began to see signs of life, and by winter, it was fully growing again. By last Spring, we had so many sprouts that we divided the bulbs and shared them with numerous friends. This year, I can see that we will again have plenty to share next Spring. This is a lush, productive plant! We keep ours in big pots because it is a bamboo like plant, will spread out of control if not contained. It loves reproducing!

Shampoo Ginger

Shampoo ginger (aka pine cone lily or pine cone ginger) adds a tropical flair to the landscape and can be used in the shower. Its foliage looks comparable to other gingers, but the inflorescence is where it gets interesting. In the fall, the flowers appear within bracts that resemble red pine cones. As the name implies, squeezing these cones causes them to release a clear liquid that can be bottled and used as shampoo!
Characteristics
Shampoo ginger (Zingiber zerumbet) is semi-evergreen and grows in large clumps that are up to seven feet tall and six feet wide. It thrives in zones 9 through 11 and will die back in the winter. The leaves are 8 to 12 inches long and lanceolate in shape. Foliage appears in the spring, and it can be either solid green or variegated depending on the variety. ‘Darceyi’ is particularly showy with green and white foliage.
In the fall, three- to five-inch-long inflorescences resembling pinecones appear on stalks that are just under a foot tall. They start out green with white flowers, then ripen to scarlet and fill with liquid. The cones have a sweet fragrance and are highly favored for floral arrangements. They will persist for weeks if left on the plant.
Planting and Care

Shampoo ginger can be planted year-round. It works as a specimen plant, border, or accent plant. You can also plant it in containers indoors or outdoors.
The ideal planting site is in partial shade to partial sun, with moist, fertile soil. Shampoo ginger is moderately salt and drought tolerant. Pests and diseases are rarely an issue, but you may encounter mites. Shampoo ginger makes an excellent passalong plant since it is propagated by division.
Once your cones have turned red, they’re ready to harvest! To collect the “shampoo” liquid from the cones, gently squeeze them over a container. They will refill by the next day if they aren’t squeezed too hard. You can also harvest the cones and then firmly squeeze them over a container to harvest all the liquid. Just keep in mind that the cones will be spent after this method. If you’re harvesting in advance, you can freeze the shampoo liquid for later.
