Botanical description of turmeric
Turmeric is a perennial plant from 60 centimeters to 1.5 meters high. It has thickened rhizomes, finger-shaped, that is to say, underground stems with several buds, and grows horizontally.
From rhizome roots and herbaceous plant shoots arise. Rhizome supports the plant because it is rich in starch, so it is also the part that is consumed in the kitchen. It can remind us the ginger rhizome, cylindrical in shape, color and with a distinctive bright orange or yellow inside. Its surface is gray, brownish or yellowish color.
It is a stemless plant, that is, it has no stem and leaves arise directly outside from rhizome
The Latin name of the plant, Curcuma longa, refers to the leaves with long petioles, oblong limbo, large and thin. Measuring 20 to 70 centimeters long and 8-18 cm wide, although some somples can reach sizes up to 1.2 meters.
Its inflorescence is terminal, spike- shaped and cylindrical, bearing spikes up to 20cm long. They have laterally green united bracts with reddish spots.
Its flowers are zygomorphic, hermaphrodite and bracteate. The calyx is tubular, with three sepals and a crown made up of three petals, yellow or white.
