Pentanema squarrosum, known as ploughman's-spikenard, [1] is a species of plant in the family Asteraceae found in Europe, North Africa, and the Near East. [2] [3]
It is a tall, hairy plant (to 1.2 m) that grows on calcareous, low-nutrient, well-drained soils. It is a short lived perennial plant. Before flowering, the basal rosette of leaves resembles those of foxgloves. It flowers after mid-summer in Europe, from July to September. [3] When in flower, the plant has many small flowerheads grouped together into a flat-topped structure that resembles a single flowerhead (pseudanthium). The individual flowerheads have prominent yellow disc florets and no (or inconspicuous) ray florets. [4]
The leaves are burned and used as an insecticide and parasiticide, especially against fleas. Even the smell of the plant is flea repellent. When the root is burned, it becomes a useful room scent (it is used this way in Turkey). [5]
Daucus carota, whose common names include wild carrot, European wild carrot, bird's nest, bishop's lace, and Queen Anne's lace, is a flowering plant in the family Apiaceae. It is native to temperate regions of the Old World and was naturalized in the New World.
Matricaria discoidea, commonly known as pineappleweed, wild chamomile, disc mayweed, and rayless mayweed, is an annual plant native to North America and introduced to Eurasia where it grows as a common herb of fields, gardens, and roadsides. It is in the daisy family Asteraceae. The flowers exude a chamomile/pineapple aroma when crushed. They are edible and have been used in salads and to make herbal tea.
Gundelia or tumble thistle is a low to high (20–100 cm) thistle-like perennial herbaceous plant with latex, spiny compound inflorescences, reminiscent of teasles and eryngos, that contain cream, yellow, greenish, pink, purple or redish-purple disk florets. It is assigned to the family Asteraceae. Flowers can be found from February to May. The stems of this plant dry-out when the seeds are ripe and break free from the underground root, and are then blown away like a tumbleweed, thus spreading the seeds effectively over large areas with little standing vegetation. This plant is native to the eastern Mediterranean and the Middle-East. Opinions differ about the number of species in Gundelia. Sometimes the genus is regarded monotypic, Gundelia tournefortii being a species with a large variability, but other authors distinguish up to nine species, differing in floret color and pubescence. Young stems are cooked and eaten in the Middle-East and are said to taste like a combination of artichoke and asparagus.
Bellis perennis, the daisy, is a European species of the family Asteraceae, often considered the archetypal species of the name daisy. To distinguish this species from other plants known as daisies, it is sometimes qualified or known as common daisy, lawn daisy or English daisy.

It is widespread across the temperate Northern Hemisphere, throughout North America and Eurasia. The species was first formally described by Carl Linnaeus in 1753 as Gnaphalium sylvaticum.
