Rocket: curiosities, properties and benefits for the body
Arugula or rocket is a plant with a pungent taste that is part of the Brassicaceae family, like cabbage and broccoli. Cultivated and appreciated throughout the Mediterranean since ancient times, this herbaceous plant is the ideal choice for the body, being low in calories and rich in nutritional and therapeutic properties.
It is important, first of all, to make a distinction between the cultivated rocket, Eruca vesicaria, and the wild rocket, Diplotaxi tenuifolia. Although they belong to the same family, and are often confused, they are actually two different species. The main difference is in the flavor and color of the leaves and flowers. The cultivated rocket, with white flowers and purple reflections, has softer and more intense green leaves. Wild rocket, on the other hand, has deep yellow flowers, harder, longer and more jagged leaves and a much stronger taste.
The history of rocket: aphrodisiac and therapeutic plant
The history of rocket has its roots in antiquity. Already in Roman times it was cultivated and appreciated for flavoring food and for its beneficial properties for the stomach and diuresis. Defined by Ovid herba salax (luxurious herb), rocket was revered for its aphrodisiac properties, a reputation that distinguished it throughout the Middle Ages. Precisely in this era of obscurantism, rocket was banned from convent gardens. Grown in Italy, Northern Europe, North America and even India, the taste and beneficial properties of rocket have allowed it to experience a new success in more recent times. In fact, the rocket of the Piana del Sele has recently also received the prestigious recognition of the Protected Geographical Indication, testifying to the uniqueness of this salad.
How rocket is grown today
The rocket is characterized by green leaves, with serrated edges and an oblong shape. The plant can grow up to 50 centimeters in height and its unmistakable spicy flavor mainly depends on the type of soil it is grown in and the growing season. The rocket, in fact, adapts well to different soils, but the more arid these are and the later the harvest will be, the more intense and pungent the flavor of the leaves will be. Stagnant water, droughts and frosts are the main enemies of this vegetable.
The sowing of the rocket takes place from March to September, but thanks to good cultivation techniques, such as those adopted by Altamura OP, the period is now extended to the whole year, while the harvest of the leaves usually starts after a month from sowing, when these are now well developed.
