Tuberaria lignosa is a perennial herb, often woody towards the base. It reaches a height of 57 centimetres (22 in) and branches freely. Its leaves are simple, 3–10 cm (1–4 in) long and 0.9–3.4 cm (0.4–1.3 in) wide. The inflorescence is lax, with each flower 2–3 cm (0.8–1.2 in) in diameter.[2]
Distribution and ecology
Tuberaria lignosa is found around the western Mediterranean Basin, in parts of Italy, France, mainland Spain, Portugal, Morocco, Tunisia, Algeria and the Canary Islands.[3]
The plant has been researched for medical purposes in cancer treatment. An aqueous extract of Tuberaria lignosa inhibited cell growth, altered the cell cycle profile, and induced apoptosis of NCI-H460 Tumor Cells.[4]
