Question: Which plant in native to northern Africa, Lamium or Hieracium?
Context: Glaucium flavum (yellow hornpoppy or yellow horned poppy) is a summer flowering plant in the Papaveraceae family, which is native to Northern Africa, Macronesia, temperate zones in Western Asia and the Caucasus, as well as Europe.  Habitat: the plant grows on the seashore and is never found inland.  All parts of the plant, including the seeds, are toxic and can produce a range of symptoms up to and including respiratory failure resulting in death FDA poisonous plants database.  It is a noxious weed in some areas of North America, where it is an introduced species.  The thick, leathery deeply segmented, wavy, bluish-grey leaves are coated in a layer of water retaining wax.  The sepal, petals and stamen have a similar structure and form to the Red Poppy (Papaver rhoeas) except the sepals are not hairy.  Prolific quantities of seeds are held in a distinctive horn shaped fruit some 15 to 30 cm in length, which is divided into two chambers. known by the common name hawkweed and classically as hierakion (from ancient Greek ιεράξ, "hierax" 'hawk'), Sisymbrium altissimum is a species of "Sisymbrium".  The plant is native to the western part of the Mediterranean Basin in Europe and Northern Africa and is widely naturalized throughout most of the world, including all of North America.  It was probably introduced into North America by a contaminant crop seed.  The plant grows in soils of all textures, even sand.  The plant germinates in winter or early spring.  The blooming time is lengthy, and after maturity the plant forms a tumbleweed.  Common names of the plant include Jim Hill mustard, after James J. Hill, a Canadian-American railroad magnate, tall tumblemustard, tall mustard, tumble mustard, tumbleweed mustard, tall sisymbrium, and tall hedge mustard. Lamium galeobdolon, commonly known as yellow archangel, artillery plant, or aluminium plant, is a widespread wildflower in Europe, and has been introduced elsewhere as a garden plant.  It displays the zygomorphic flower morphology, opposite leaves, and square stems typical of the mint family, Lamiaceae.  The flowers are soft yellow and borne in axial clusters, with a prominent 'hood' (the dorsal lobe of the corolla).  It spreads easily and so has been commonly used as an ornamental ground cover.  It can be invasive in places where it is not native and caution must be taken when planting in these areas. Chrysopogon nigritanus, more widely known by the taxonomic synonym Vetiveria nigritana, or the common name black vetivergrass, is a perennial grass species of the Poaceae family and therefore is also a monocotyledon.  More specifically, "Vetiveria nigritana" is a very thick and tall type of grass that is deeply rooted within the ground and is usually used to protect crops and deter soil erosion.  "Vetiveria nigritana" is also a native species to Africa and is most commonly seen in Nigeria, Northern Africa, Eastern Africa and tropical parts of Southern Africa.  In addition, the plant, like other vetiver grasses, has been used in these regions due to its extreme drought tolerance, ability to grow in infertile soil and the fact that it can live under complete submergence.  In fact, "Vetiveria nigritana" can thrive in a very diverse range of environmental and climatic conditions. Hieracium pilosella (syn.  "Pilosella officinarum"), known as mouse-ear hawkweed, is a yellow-flowered species of flowering plant in the daisy family Asteraceae, native to Europe and northern Asia.  It produces single, lemon-coloured inflorescences.  It is an allelopathic plant.  Like most hawkweed species, it is highly variable and is a member of a species complex of several dozens of subspecies and hundreds of varieties and forms. Hieracium canadense, commonly called Canadian hawkweed, Canada hawkweed, narrowleaf hawkweed, or northern hawkweed, is a plant in the genus "Hieracium".  Its pointed leaves have toothed margins, where the teeth can appear almost hooked.  The flowers of the plant are yellow. Hen and chicks (also known as hen-and-chickens, or hen-and-biddies in the American South) is a common name for a group of small succulent plants belonging to the flowering plant family Crassulaceae, native to southern Europe and northern Africa.  They grow close to the ground with leaves formed around each other in a rosette, and propagating by offsets.  The "hen" is the main plant, and the "chicks" are the offspring, which start as tiny buds on the main plant and soon sprout their own roots, taking up residence close to the mother plant. Lamium amplexicaule, commonly known as henbit dead-nettle, common henbit, or greater henbit, is a species of "Lamium" native to Europe, Asia and northern Africa. Lamium (dead-nettles) is a genus of about 40–50 species of flowering plants in the family Lamiaceae, of which it is the type genus.  They are all herbaceous plants native to Europe, Asia, and northern Africa, but several have become very successful weeds of crop fields and are now widely naturalised across much of the temperate world.
Answer: Lamium
