Yucca is a genus of perennial shrubs and trees in the family Asparagaceae, subfamily Agavoideae. Its 40–50 species are notable for their rosettes of evergreen, tough, sword-shaped leaves and large terminal panicles of white or whitish flowers. They are native to the Americas and the Caribbean in a wide range of habitats, from humid rainforest and wet subtropical ecosystems to the hot and dry (arid) deserts and savanna.
Hyacinthoides non-scripta is a bulbous perennial plant found in Atlantic areas from the north-western part of the Iberian Peninsula to the British Isles, and also frequently used as a garden plant. It is known in English as the common bluebell or simply bluebell, a name which is used in Scotland to refer to the harebell, Campanula rotundifolia. In spring, H. non-scripta produces a nodding, one-sided inflorescence of 5–12 tubular, sweet-scented violet–blue flowers, with strongly recurved tepals, and 3–6 long, linear, basal leaves.
Sassafras is a genus of three extant and one extinct species of deciduous trees in the family Lauraceae, native to eastern North America and eastern Asia. The genus is distinguished by its aromatic properties, which have made the tree useful to humans.
Hypericum perforatum, commonly known as St John's wort, is a flowering plant in the family Hypericaceae. It is a perennial plant that grows up to 1 metre tall, with many yellow flowers that have clearly visible black glands around their edges, long stamens, and three pistils. Probably a hybrid between the closely related H. attenuatum and H. maculatum that originated in Siberia, the species is now found worldwide. It is native to temperate regions across Eurasia and North Africa, and has been introduced to East Asia, Australia, New Zealand, and parts of North and South America. In many areas where it is not native, H. perforatum is considered a noxious weed. It densely covers open areas to the exclusion of native plants, and is poor grazing material. As such, methods for biocontrol have been introduced in an attempt to slow or reverse the spread of the species.
Liquidambar, commonly called sweetgum, gum, redgum, satin-walnut, styrax or American storax, is the only genus in the flowering plant family Altingiaceae and has 15 species. They were formerly often treated as a part of the Hamamelidaceae. They are native to southeast and east Asia, the eastern Mediterranean and North America. They are decorative deciduous trees that are used in the wood industry and for ornamental purposes.
Watercress or yellowcress is a species of aquatic flowering plant in the cabbage family, Brassicaceae.
Camassia quamash, commonly known as camas, kwetlal, small camas, common camas, common camash or quamash, is a perennial herb. It is native to western North America in large areas of southern Canada and the northwestern United States.
Photoperiod is the change of day length around the seasons. The rotation of the earth around its axis produces 24 hour changes in light (day) and dark (night) cycles on earth. The length of the light and dark in each phase varies across the seasons due to the tilt of the earth around its axis. The photoperiod defines the length of the light, for example a summer day the length of light could be 16 hours while the dark is 8 hours, whereas a winter day the length of day could be 8 hours, whereas the dark is 16 hours. Importantly, the seasons are different in the northern hemisphere than the southern hemisphere.
Pandanus tectorius is a species of Pandanus (screwpine) that is native to Malesia, Papuasia, eastern Australia, and the Pacific Islands. It grows in the coastal lowlands typically near the edge of the ocean. Common names in English include thatch screwpine, Tahitian screwpine, hala tree and pandanus. The fruit is edible and sometimes known as hala fruit.
Elodea canadensis is a perennial aquatic plant, or submergent macrophyte, native to most of North America. It has been introduced widely to regions outside its native range and was first recorded from the British Isles in about 1836.

The Australian Native Plants Society (Australia) (ANPSA) is a federation of seven state-based member organisations for people interested in Australia's native flora, both in aspects of conservation and in cultivation.
Mandragora officinarum is the type species of the plant genus Mandragora in the nightshade family Solanaceae. It is often known as mandrake, although this name is also used for other plants. As of 2015, sources differed significantly in the species they use for Mandragora plants native to the Mediterranean region. The main species found around the Mediterranean is called Mandragora autumnalis, the autumn mandrake. In a broader circumscription, all the plants native to the regions around the Mediterranean Sea are placed in M. officinarum, which thus includes M. autumnalis. The names autumn mandrake and Mediterranean mandrake are then used. Whatever the circumscription, Mandragora officinarum is a perennial herbaceous plant with ovate leaves arranged in a rosette, a thick upright root, often branched, and bell-shaped flowers followed by yellow or orange berries.
Bismarckia is a monotypic genus of flowering plant in the palm family with Bismarckia nobilis being the only species in the genus and is endemic to western and northern Madagascar, where it grows in open grassland.
Nepeta cataria, commonly known as catnip and catmint, is a species of the genus Nepeta in the mint family, native to southern and eastern Europe, the Middle East, and Central Asia. It is widely naturalized in northern Europe, New Zealand, and North America. The common name catmint can also refer to the genus as a whole.
Aphandra is a monotypic genus of flowering plants in the palm family native to the Amazon rainforest vegetation in South America. Its only species is Aphandra natalia, sometimes called mastodon palm or fiber palm, and is used by indigenous peoples in the construction of brooms and other products. This plant is commercially exploited for its edible fruits, and for its leaf sheath and petiole fibers. This fiber is almost equal to the fiber extracted from Attalea funifera and Leopoldinia piassaba, which is called piassava.
Erythrostemon mexicanus, formerly Caesalpinia mexicana, is a species of plant in the genus Erythrostemon, within the pea family, Fabaceae. Common names include Mexican holdback, Mexican caesalpinia, and tabachín del monte. It is native to the extreme lower Rio Grande Valley of Texas and to parts of Mexico: in the northeast and further south along the Gulf coast as well as the Pacific coast in Nayarit, Jalisco, Colima, and a small portion of Sinaloa.
Sabal mexicana is a species of palm tree that is native to far southern North America. Common names include Rio Grande palmetto, Mexican palmetto, Texas palmetto, Texas sabal palm, palmetto cabbage and palma de mícharos. The specific epithet, "mexicana", is Latin for "of Mexico."
Quercus geminata, commonly called sand live oak, is an evergreen oak tree native to the coastal regions of the subtropical southeastern United States, along the Atlantic Coast from southern Florida northward to southeastern Virginia and along the Gulf Coast westward to southern Mississippi, on seacoast dunes and on white sands in evergreen oak scrubs.
