Diplotaxis tenuifolia (L.) DC.: a diploid and perennial species, in the sense that the roots can survive winters and produce new sprouts in the next spring; it flowers from late spring to autumn and its seeds are generally ready for collecting in autumn. It seems to be very well adapted to harsh and poor soils, and often it can compete well with other species in calcareous shallow soils. This species has succulent leaves and is much apprciated in cuisine. In some Italian areas D. tenuifolia is also cultivated, but it is mostly collected from the wild and sold in small bunches in local markets.

Diplotaxis muralis (L.) DC.: polyploid and perennial, in the same sense as D. tenuifolia. It flowers from summer to autumn and its seeds are ready for sollecting in autumn. It grows in similar habitats as D. tenuifolia and is also collected from the wild to be sold in the markets. It seems less adapted to cultivation because of its procumbent growth habit, which is the main character distinguishing it from D. tenuifolia.
