Plants are 30 to 150 cm (to in) 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.

Opuntia, also known as nopales or paddle cactus, is a genus in the cactus family, Cactaceae. Currently, only prickly pears are included in this genus of about 200 species distributed throughout most of the Americas. Chollas are now separated into the genus Cylindropuntia, which some still consider a subgenus of Opuntia. Austrocylindropuntia, Corynopuntia, and Micropuntia are also often included in the present genus, but like Cylindropuntia, they seem rather distinct. Brasiliopuntia and Miqueliopuntia are closer relatives of Opuntia.

Chives is the common name of Allium schoenoprasum, the smallest species of the edible onions. A perennial plant, it is native to Europe, Asia and North America. A. schoenoprasum is the only species of Allium native to both the New and the Old Worlds. The name of the species derives from the Greek skhoínos and práson.
