Erinus is a genus of flowering plants in the family Plantaginaceae (previously in the family Scrophulariaceae), native to stony mountainous sites in North Africa and southern Europe.
 Some members of the genus have been cultivated as ornamental plants, particularly "Erinus alpinus", for which a number of different cultivars are available.
Safflower ("Carthamus tinctorius") is a highly branched, herbaceous, thistle-like annual plant.
 It is commercially cultivated for vegetable oil extracted from the seeds. Plants are 30 to tall with globular flower heads having yellow, orange, or red flowers. Each branch will usually have from one to five flower heads containing 15 to 20 seeds per head.
 Safflower is native to arid environments having seasonal rain.
 It grows a deep taproot which enables it to thrive in such environments.
