8 most common species:
Elymus glaucus
Blue wild rye
Blue wild rye is a common species of wild rye native across the United States. Its blue-green blades grow in small bunches up to 1.5 m tall. It is valuable for erosion control and reforestation projects.
Elymus tsukushiensis
Wheatgrass
As a guideline ears appear in early summer and spikes with no pattern are arranged on the ears and the ears are slightly flat and elongated and well-developed buds are facing upwards. However there are many approximate species. The stalk grows up slightly to the side at the base and rises to 40 to 100 cm. The leaves are 20 to 30 cm long and 5 to 10 mm wide emerging from the stem nodes green and not shiny. The flowering period is from spring to summer and the ears rise from the tip of the stem and rise to a bow. A spike-like inflorescence with a small spike along the stem. The spikelet is upward along the axis and the length is 1.5 to 2.5 cm. It is slightly flat and long and contains 5-10 florets. The color is green and white as if powdered and it is usually purple. The cocoon that extends from the tip of the pallet is 1.5 to 3 cm long and many are purple. The cocoon grows smoothly toward the tip of the ear and does not warp when dried.
Elymus canadensis
Canada Wildrye
Elymus canadensis is a species of wild rye that's native to North America. It's widely found in the central part of the continent and the Great Plains. The plant can grow in several different habitats, like woodlands, dunes, prairies and areas that have been disturbed. Canada Wildrye is often used to stabilize eroded areas as well as for vegetating metal-rich soils.
Elymus repens
Quack grass
Quack grass (Elymus repens) spreads quickly using creeping rhizomes. This has led to its use as a forage crop and erosion control plant in many places outside its native habitat. In some countries, including the USA, it has proved to spread too quickly, and is now classed as an invasive that crowds out native species.
Elymus villosus
Hairy wild rye
Hairy wild rye (Elymus villosus) is a native grass of the eastern USA. It favors damp woodlands and small meadows. The flowers are insignificant and wind-pollinated, so do not attract insects. Birds seldom eat the seeds, and the plant is not palatable to wildlife. Livestock eat the foliage, but the bristles on the seed heads can injure their mouths and intestines.
Elymus elymoides
Squirreltail
Squirreltail (Elymus elymoides) is a type of rye that comes from North America, and is especially common around the Mississippi River. This bunchgrass is particularly good winter forage for sheep, though it works for other livestock as well if needed. Squirreltail's bristly awns become tougher and sharper as the plant ages.
Elymus hystrix
Eastern bottle-brush grass
Elymus hystrix or eastern bottle-brush grass is part of the grass family and native to eastern North America. Mice eat the seeds readily. Studies are underway to examine whether eastern bottle-brush grass can be domesticated, as a food crop for livestock or potentially even humans in the future.
Elymus virginicus
Virginia wild rye
Virginia wild rye (Elymus virginicus) is a perennial grass that is native to the eastern United States. It grows best in moist, sunny locations with fertile soil. The foliage is a food source for various insects, some moth caterpillars, ducks, and geese; small rodents will also harvest and eat the seeds. It is sometimes planted on hillsides for erosion control.

Western wheat grass
Elymus smithii
Western wheat grass
The western wheat grass (Elymus smithii) is a type of grass that provides food for foraging bison and livestock. It is a good first-colonizer species that can be used to regrow disturbed and barren soil. This grass looks similar to Beardless Wildrye but can be differentiated by its spikelets, which are typically single rather than double.
Baker's wheatgrass
Elymus bakeri
Baker's wheatgrass
Elymus bakeri, or baker's wheatgrass as it is commonly called, is native to the mountains and meadows of the western United States, including in Utah, Montana, Oregon, Washington, Wyoming, Colorado, Idaho, and New Mexico. It is found growing in higher meadows.
Dahurian wildrye
Elymus dahuricus
Dahurian wildrye
The dahurian wildrye is a short-lived perennial grass that makes an excellent forage plant for livestock, similar to Altai and Giant wild rye. Very nutritional and highly palatable, this plant establishes itself quickly after grazing and can be grazed two or three times per season. It is also a great candidate for soil erosion control.
Wildrye
Elymus ciliaris
Wildrye
Wildrye is a grass species that typically features dense tufts and long, slender, flat blades with distinctive, slightly feathered edges. This perennial plant often exhibits a robust root system, allowing it to thrive in various, even harsh, environmental conditions. It displays tall, erect stems topped with spike-like inflorescences during its blooming period, contributing to its resilience by aiding in effective seed dispersion.

Dracaena
Dracaena
Dracaena are popular house plants that are easy to grow. They can tolerate low-light conditions and require little watering. Their leaves range from variegated to dark green. Their characteristic traits include woody stems that grow slowly but offer a striking appearance for small spaces such as apartments or offices.
Ficus
Fig trees
Fig trees have been cultivated in many regions for their fruits, particularly the common fig, F. carica. Most of the species have edible fruits, although the common fig is the only one of commercial value. Fig trees are also important food sources for wildlife in the tropics, including monkeys, bats, and insects.
Rubus
Brambles
Brambles are members of the rose family, and there are hundreds of different types to be found throughout the European countryside. They have been culturally significant for centuries; Christian folklore stories hold that when the devil was thrown from heaven, he landed on a bramble bush. Their vigorous growth habit can tangle into native plants and take over.
Acer
Maples
The popular tree family known as maples change the color of their leaves in the fall. Many cultural traditions encourage people to watch the colors change, such as momijigari in Japan. Maples popular options for bonsai art. Alternately, their sap is used to create maple syrup.
Prunus
Prunus
Prunus is a genus of flowering fruit trees that includes almonds, cherries, plums, peaches, nectarines, and apricots. These are often known as "stone fruits" because their pits are large seeds or "stones." When prunus trees are damaged, they exhibit "gummosis," a condition in which the tree's gum (similar to sap) is secreted to the bark to help heal external wounds.
Solanum
Nightshades
Nightshades is a large and diverse genus of plants, with more than 1500 different types worldwide. This genus incorporates both important staple food crops like tomato, potato, and eggplant, but also dangerous poisonous plants from the nightshade family. The name was coined by Pliny the Elder almost two thousand years ago.
Rosa
Roses
Most species of roses are shrubs or climbing plants that have showy flowers and sharp thorns. They are commonly cultivated for cut flowers or as ornamental plants in gardens due to their attractive appearance, pleasant fragrance, and cultural significance in many countries. The rose hips (fruits) can also be used in jams and teas.
Quercus
Oaks
Oaks are among the world's longest-lived trees, sometimes growing for over 1,000 years! The oldest known oak tree is in the southern United States and is over 1,500 years old. Oaks produce an exceedingly popular type of wood which is used to make different products, from furniture and flooring to wine barrels and even cosmetic creams.
