Diplotaxis tenuifolia. 'Rocky' is a fast-growing, wild-type arugula that grows in a compact rosette form. Wild arugula has a slightly stronger, more complex flavor than regular arugula, and is perennial in USDA zones 6—10. Its flavor can be described as peppery or mustardy with a hint of nuttiness. Most often eaten raw in salads, arugula can also give pizzazz to pizza or be enjoyed simply steamed.[1[

Common Problems, Diseases and Pests
Arugula bolts (goes to flower) most commonly in response to warm or hot weather, uneven soil moisture, wilting, or soil dryness. Overharvesting, rootbinding, and other stressors may also encourage arugula to bolt early. There is nothing that can be done to reverse or stop bolting once it begins; it may be possible to extend harvest slightly by cutting off flower stalks as they appear. It is recommended to tasting leaves for quality and if still reasonable, harvesting the majority of leaves or whole plants at the first sign of bolting, unless you want to save seeds.
