Botanical description of rocket
The name of rocket or arugula hides three different species: the perennial wall-rocket (Diplotaxis tenuifolia L.), annual wall-rocket (Diplotaxis muralis L.) and arugula or rocket (Eruca vesicaria L.).
Eruca vesicaria) es una hierba anual que mide de 15 a 50 centímetros de altura (hasta 1 metro si se las deja crecer).">Rocket (Eruca vesicaria) is an annual herb that measures 15 to 50 inches high (up to 1 meter if left to grow). It is characterized by dense rough hairs covering the stem.
Leaves deeply divided into toothed segments that can reach the central leaf, lyrate-pinnatifid to pinnatisect. Size between 7.6 and 18 inches long. Arugula leaves are edible (young plants under 30 inches tall) and have a strong smell (due to their glucosinolate content).
It blooms in spring, between April and May in the northern hemisphere. The inflorescence emerges from a flower stalk that can measure between 60 and 90 centimeters high. It is crowned with white flowers in clusters, cross-shaped, composed of four petals whitish or yellowish, between 15 and 20 millimeters, with veins dark brown to purple. Sepals 7 to 12 mm, persistent until fruit maturity at times.
The fruits are elongated pods that end in a sort of beak reddish, attached to the stem with a size between 1 to 2.5 inches long and about 4 to 6 millimeters wide. They are erect, glabrous (or sometimes hispid) with a protruding vein on each face and pointed.
At maturity, the fruits open and show the inside where two sets of tiny round seeds (biseriate) appear. they are between 1.5 and 2 mm in diameter each, slightly flattened and ocher.
Rocket reproduces by seed and can be grow in warm areas.

Although this plant has become popular for use in salads, in the past, the ripe fruits were collected before they opened to get their seeds.
Plant seeds contain 30% oil and a spicy sulfurous essence, similar to that provided by mustard (Brassica nigra - also a crucifer).
