Alpinia zerumbet SHELL GINGER (plant)

Shell Ginger or Alpinia zerumbet in Latin, belongs to the Zingiberaceae family.
It is a tropical, perennial, rhizomatous herbaceous plant native to East Asia.
At maturity, it stands about 70 cm tall.

Its foliage is highly aromatic with a scent close to cinnamon, which is why it is also nicknamed "Cinnamon Ginger."
The leaves measure 30 to 40 cm in length and are lance-shaped, simple, upright, and very glossy.

The flowering of the Alpinia zerumbet begins late in the year.
Its sweet-scented flowers grow in drooping clusters and feature shades of yellow, white, and pink.

Shell Ginger seeds are round and black, measuring 5 millimeters in diameter, and are surrounded by white flesh.

Cultivation and Strictly Ornamental Use

Ideal for mild climates outdoors or container cultivation in cooler regions, this variety brings an immediate tropical signature.
For safety reasons, this specimen is intended exclusively for ornamentation, botanical observation, and aromatic use of the foliage (ambient fragrance). 

- Cultivation and Planting:

• Plant shell ginger in a 5-liter pot just above the collar.
• Use a fine, well-draining peat-based potting soil. Add a small bed of clay pebbles at the bottom to facilitate drainage.
• Water gently at the base of the plant.
• Place the plant in a warm, bright spot so it can grow correctly.

- Soil and Substrate:

It grows in soil rich in organic matter. The substrate must be light, well-aerated, and above all, well-draining.

- Light and Exposure:

This aromatic rhizome plant needs plenty of bright light. It should be placed in a sunny or slightly shaded location to thrive.

- Watering and Irrigation:

It enjoys frequent watering but does not like "wet feet." It is necessary to water it at least 3 times a week during the height of summer, making sure that no stagnant water remains in the pot's saucer.

- Temperatures and Hardiness:

Its exotic origin allows it to grow very well in temperatures ranging from 25°C to 35°C. Below 15°C, the plant stops developing.
This variety is not very hardy; the base freezes at 0°C and the plant dies. It is therefore imperative to bring it indoors before the winter period.

- Propagation:

Atoumo can be multiplied by dividing its rhizomes, which is the simplest and fastest way to reproduce it.
Sowing seeds is also possible starting in late spring.

- Pests and Diseases:

This plant is very resistant to diseases. It is rarely attacked by pests, with the exception of spider mites if grown in a greenhouse.

- Maintenance:

Prune yellow leaves as the plant grows. An application of fertilizer once a year is helpful if it is grown in a pot.
