Perennial rocket is also known by several other common names, including Sisymbrium irio, London rocket, and tansy mustard.
One of the most striking features of perennial rocket is its unique foliage. The leaves are narrow and deeply lobed, with a slightly hairy texture. The plant typically grows up to 60 cm in height, and it produces small white or yellow flowers that bloom in clusters from late spring to early summer. The seeds of perennial rocket are small and black, and they are often used in cooking as a spice.
Perennial rocket is a hardy plant that can tolerate a range of growing conditions. It prefers well-drained soil and full sun, but it can also thrive in partially shaded areas.
