Turmeric, a spice hidden underground

Turmeric (Curcuma longa) is best known as the orange-yellow powder used in cooking. However, it comes from a tropical plant with lush foliage, where the sought-after part grows underground. As with ginger, it is not a root but a rhizome, which is an underground stem capable of producing new shoots.

Once harvested, the turmeric rhizome can be used fresh or processed to create the powdered spice. Its characteristic color is primarily due to the presence of curcuminoids, including curcumin. This strong pigmentation also explains its long-standing use as a natural dye.

Turmeric holds an important place in many Asian cuisines and has spread widely throughout tropical regions. In the Caribbean, it is also grown and used to add color and flavor to dishes, sauces, marinades, and various preparations. It can also be found in certain drinks and infusions.

The plant has another surprise in store: its flowering. Its inflorescences are composed of overlapping bracts, between which small flowers appear. They serve as a reminder that turmeric belongs to the Zingiberaceaefamily, just like theshell ginger and the spectacular torch ginger.

At the Jardin de Valombreuse, turmeric offers a chance to discover the plant behind a familiar spice and to observe the astonishing diversity of aromatic plants grown in the tropical climate of Guadeloupe.
