- Acaena — A genus of perennial herbaceous or subshrubby plants in the Rosaceae family, primarily native to the Southern Hemisphere, remarkable for their ability to form dense, persistent, and highly resilient evergreen groundcovers. Morphologically, they are distinguished by fine, often pinnate foliage and globose inflorescences whose fruits develop spines or burrs adapted for zoochory (dispersal by attaching to animal fur).
- Arctostaphylos nevadensis — An endemic species of trailing shrub in the genus Arctostaphylos, commonly known as the pinemat manzanita. The plant structurally grows in dense mats at high elevations in the Cascade and Sierra Nevada mountains of western North America, featuring flexible branches that root upon soil contact, small, shiny green elliptical leaves, and urn-shaped white or pink flowers, acting as an essential ecological component for stabilizing eroded alpine soils.
- Arenaria montana — A species of perennial herbaceous plant in the Caryophyllaceae family, native to the mountainous regions of southwestern Europe, commonly known as mountain sandwort. The plant is structurally characterized by trailing stems forming dense mats, small, lanceolate, deep green leaves, and abundant flowers with five immaculate snow-white petals, widely used in horticulture for decorating rockeries and alpine gardens due to its high resilience.
- Arundinaria viridistriata — The scientific name of a dwarf bamboo species highly valued for its variegated leaves striped with yellow and green (currently known taxonomically as Pleioblastus viridistriatus). This ornamental plant from the Poaceae family features a low, compact structural growth pattern, making it ideal as a groundcover in partially shaded areas of urban gardens due to its bold color contrast.
- European wild ginger — The scientific name of a perennial herbaceous plant in the Aristolochiaceae family, commonly known as European wild ginger. The plant grows wild in shaded deciduous forests across Europe, featuring glossy kidney-shaped leaves and creeping rhizomes with a peppery scent, historically used in traditional medicine despite containing asarone, a substance with high toxic potential.
- Asarum virginicum — A species of evergreen perennial herbaceous plant native to the southeastern United States, historically known in taxonomy under this academic name and currently classified as Hexastylis virginica. Characterized structurally by its persistent, heart-shaped leaves with a striking mottled pattern and unique flowers hidden close to the ground, it is appreciated in niche horticulture for its shade tolerance and decorative groundcover qualities.
- Asperula odorata — The scientific name (a taxonomic synonym frequently used for Galium odoratum) of a perennial herbaceous plant in the family Rubiaceae, commonly known as sweet woodruff; it grows in beech and deciduous forests, famous for its small, white, fragrant flowers and high coumarin content, a volatile structural compound that gives it a pleasant scent of fresh hay when dried, used in the perfume industry and traditional medicine.
- Aubrieta deltoidea — The type species of perennial flowering plant in the genus Aubrieta, family Brassicaceae, native to southeastern Europe and widely cultivated as an ornamental; Lilac bush or rock cress. It is characterized by low-growing, mat-forming habits, slightly toothed deltoid leaves, and abundant violet or pink-purple flowers covering the foliage in early spring.
