Banksia is a genus of around 170 species in the plant family Proteaceae. These Australian wildflowers and popular garden plants are easily recognised by their characteristic flower spikes and fruiting "cones" and heads. Banksias range in size from prostrate woody shrubs to trees up to 30 metres tall. They are found in a wide variety of landscapes: sclerophyll forest, (occasionally) rainforest, shrubland, and some more arid landscapes, though not in Australia's deserts.
In botany, a drupe is an indehiscent fruit in which an outer fleshy part surrounds a single shell of hardened endocarp with a seed (kernel) inside. These fruits usually develop from a single carpel, and mostly from flowers with superior ovaries.
Euonymus is a genus of flowering plants in the staff vine family, Celastraceae. Common names vary widely among different species and between different English-speaking countries, but include spindle, burning-bush, strawberry-bush, wahoo, wintercreeper, or simply euonymus. It comprises about 130 species of deciduous and evergreen shrubs, small trees and lianas. They are mostly native to East Asia, extending to the Himalayas, and they are also distributed in Europe, Australasia, North America, and Madagascar. 50 species are endemic to China.
Persicaria perfoliata is a species of flowering plant in the buckwheat family. Common names include mile-a-minute, devil's tail, giant climbing tearthumb, and Asiatic tearthumb. It is a trailing herbaceous annual vine with barbed stems and triangular leaves. It is native to most of temperate and tropical eastern Asia, occurring from eastern Russia and Japan in the north, and the range extending to the Philippines and India in the south. P. perfoliata is an aggressive, highly invasive weed.
Cirsium vulgare, the spear thistle, bull thistle, or common thistle, is a species of the Asteraceae genus Cirsium, native throughout most of Europe, Western Asia, and northwestern Africa. It is also naturalised in North America, Africa, and Australia and is an invasive weed in some areas. It is the national flower of Scotland.
Verbascum thapsus, the great mullein, greater mullein or common mullein is a species of mullein native to Europe, northern Africa, and Asia, and introduced in the Americas and Australia.
Seed dispersal is the movement, spread or transport of seeds away from the parent plant. Plants have limited mobility and rely upon a variety of dispersal vectors to transport their propagules, including both abiotic vectors such as the wind and living (biotic) vectors like birds. Seeds can be dispersed away from the parent plant individually or collectively, as well as dispersed in both space and time. The patterns of seed dispersal are determined in large part by the dispersal mechanism and this has important implications for the demographic and genetic structure of plant populations, as well as migration patterns and species interactions. There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. Dispersal involves the letting go or detachment of a diaspore from the main parent plant.
Capsella bursa-pastoris, known as shepherd's purse because of its triangular flat fruits, which are purse-like, is a small annual and ruderal flowering plant in the mustard family (Brassicaceae). It is native to eastern Europe and Asia minor, but is naturalized and considered a common weed in many parts of the world, especially in colder climates, including British Isles, where it is regarded as an archaeophyte, North America and China, but also in the Mediterranean and North Africa. C. bursa-pastoris is the second-most prolific wild plant in the world, and is common on cultivated ground and waysides and meadows.
Acaena is a genus of about 60 species of mainly evergreen, creeping herbaceous perennial plants and subshrubs in the family Rosaceae, native mainly to the Southern Hemisphere, notably New Zealand, Australia and South America, but with a few species extending into the Northern Hemisphere, north to Hawaii and California.
A tumbleweed is a structural part of the above-ground anatomy of a number of species of plants. It is a diaspore that once it is mature and dry, detaches from its root or stem and rolls due to the force of the wind. In most such species, the tumbleweed is in effect the entire plant apart from the root system, but in other plants, a hollow fruit or inflorescence might detach instead. Xerophyte tumbleweed species occur most commonly in steppe and arid ecosystems, where frequent wind and the open environment permit rolling without prohibitive obstruction.
Acacia saligna, commonly known by various names including coojong, golden wreath wattle, orange wattle, blue-leafed wattle, Western Australian golden wattle, and, in Africa, Port Jackson willow, is a small tree in the family Fabaceae. Native to Australia, it is widely distributed throughout the south west corner of Western Australia, extending north as far as the Murchison River, and east to Israelite Bay. The Noongar peoples know the tree as Cujong.
A bur is a seed or dry fruit or infructescence that has hooks or teeth. The main function of the bur is to spread the seeds of the bur plant, often through epizoochory. The hooks of the bur is used to catch on to for example fur or fabric, so that the bur, which contain seeds, then can be transported along with the thing it attached itself to. Another use for the spines and hooks are physical protection against herbivores. Their ability to stick to animals and fabrics has shaped their reputation as bothersome.
Acacia mearnsii, commonly known as black wattle, late black wattle or green wattle, is a species of flowering plant in the family Fabaceae and is endemic to south-eastern Australia. It is usually an erect tree with smooth bark, bipinnate leaves and spherical heads of fragrant pale yellow or cream-coloured flowers followed by black to reddish brown pods. In some other parts of the world, it is regarded as an invasive species.
Senna alata is an important medicinal tree, as well as an ornamental flowering plant in the subfamily Caesalpinioideae. It also known as emperor's candlesticks, candle bush, candelabra bush, Christmas candles, empress candle plant, ringworm shrub, or candletree. A remarkable species of Senna, it was sometimes separated in its own genus, Herpetica.
Rocket or arugula is an edible annual plant in the family Brassicaceae used as a leaf vegetable for its fresh, tart, bitter, and peppery flavor. Other common names include garden rocket, and eruca. It is also called "ruchetta", "rucola", "rucoli", "rugula", "colewort", and "roquette". Eruca sativa, which is widely popular as a salad vegetable, is a species of Eruca native to the Mediterranean region, from Morocco and Portugal in the west to Syria, Lebanon, Egypt and Turkey in the east.

Taraxacum is a large genus of flowering plants in the family Asteraceae, which consists of species commonly known as dandelions. The scientific and hobby study of the genus is known as taraxacology. The genus is native to Eurasia and North America, but the two most commonplace species worldwide, T. officinale and T. erythrospermum, were introduced into North America from Europe and now propagate as wildflowers. Both species are edible in their entirety. The common name dandelion is also given to specific members of the genus.
Kil'ayim are the prohibitions in Jewish law which proscribe the planting of certain mixtures of seeds, grafting, the mixing of plants in vineyards, the crossbreeding of animals, the formation of a team in which different kinds of animals work together, and the mixing of wool with linen in garments.
Escaped plants are cultivated plants, usually garden plants, that are not originally native to an area, and due to their dispersal strategies, have escaped from cultivation and have settled in the wild and bred there, whether intentionally or unintentionally. Escaped plants are purposefully introduced plants that have naturalized in the wild and can develop into invasive plants, the settlement of which is to be assessed as problematic. Other commonly used terms include escaped garden plant, garden escapee, escaped ornamental or garden refugee.
Adventive plants or adventitious plants are plants that have established themselves in a place that does not correspond to their area of origin due to anthropogenic influence and, therefore, are all wild species that have only been established with the help of humans, in contrast to the native species.
