- Adenophora lilifolia — A species of perennial herbaceous plant native to the temperate regions of Eurasia, belonging to the Campanulaceae family. It is structurally recognized for its erect stems, lanceolate leaves with serrated margins, and rich panicle-like inflorescences containing pendulous, bell-shaped (campanulate) flowers of a pale blue or violet color, emitting a subtle fragrance and valued in ecological ornamental horticulture.
- Ageratum corymbosum — A species of perennial herbaceous plant in the genus Ageratum, native to Mexico and the southern United States, characterized by corymbose inflorescences made of small, deep-blue or violet flowers. It is occasionally used in horticulture for its ability to attract pollinators and its superior resistance in arid climates compared to annual species.
- Aglaonema — A genus of flowering plants in the arum family, Araceae, native to tropical and subtropical regions of Southeast Asia and New Guinea. These plants are highly valued worldwide as indoor ornamental plants due to their high tolerance for low light conditions and decorative foliage, which is often variegated, patterned, or tinged in complex shades of green, silver, cream, or red.
- Alonsoa linearis — The scientific Latin designation for a representative plant species within the Alonsoa genus, Scrophulariaceae family, structurally characterized by narrow, elongated, and linear leaves, completely distinct from other related species. This perennial or annual plant produces deep red or bright orange flowers, positioned resupinately on the stem, valued in landscape design for its fine and delicate structural layout.
- Alpinia — A genus of tropical and subtropical perennial herbaceous plants in the Zingiberaceae (ginger) family, distributed predominantly across Asia and the Pacific Islands. This structural taxon encompasses species with large aromatic rhizomes, vigorous pseudostems, and spectacular raceme inflorescences, widely cultivated as decorative, spice, or medicinal plants.
- Alpinia malaccensis — The scientific Latin designation for an impressive perennial herbaceous plant species within the Alpinia genus, Zingiberaceae family, native to Malaysia and Indonesia (Malacca). This large-sized plant stands out structurally due to its spectacular erect inflorescences, consisting of large, white flowers with a labellum intensely colored in bright shades of yellow and red, cultivated in tropical regions as a premium ornamental plant and for the essential oil extracted from its leaves and rhizomes.
- Alpinia speciosa — The scientific Latin designation (a synonym frequently used in literature for Alpinia zerumbet) denoting shell ginger or ginger lily, a large-sized perennial herbaceous plant species in the Zingiberaceae family, native to East Asia. This spectacular ornamental plant stands out structurally due to its long, drooping inflorescences consisting of large flowers resembling pinkish-white porcelain shells and an intensely colored labellum in bright shades of yellow and red, widely cultivated in tropical regions and greenhouses.
- Alstroemeria — A genus of perennial herbaceous plants in the Alstroemeriaceae family, native to South America (especially from mountainous regions in Chile and Brazil), popularly known as 'Peruvian lilies' or 'lilies of the Incas'. This structural taxon encompasses species recognized for their tuberous rhizomes, resupinate leaves (twisted upside down on the petiole), and intensely colored, asymmetric flowers, widely cultivated in horticulture as cut flowers due to their exceptional longevity in vases.
- Anaphalis margaritacea — The official binominal scientific name of the perennial herbaceous plant species popularly known as 'pearly everlasting', belonging to the Asteraceae family. The species is native to North America and Eastern Asia, widely appreciated for its long-lasting inflorescences made of dense capitula with white, pearly, and dry involucral bracts surrounding the yellow central disc florets. The structure of the stem and narrow leaves is covered with a dense layer of silvery, woolly hairs, providing the plant with drought resistance and a distinct aesthetic appearance.
- Anaphalis triplinervis — The official binominal scientific name of a perennial herbaceous plant species in the genus Anaphalis, family Asteraceae, native to the mountainous and alpine regions of Nepal and the Himalayas. The species is structurally distinguished by its grayish-silvery obovate or lanceolate leaves, characterized by the presence of three prominent parallel veins (hence the specific epithet triplinervis), and by corymb-like inflorescences composed of heads with dry, persistent white involucral bracts surrounding the yellow central disc florets.
