- Allamanda — A genus of flowering plants in the family Apocynaceae, native to the tropical regions of Central and South America. It comprises species of climbing shrubs and vigorous vines, widely cultivated in warm climates or greenhouses as ornamental plants due to their glossy foliage and spectacular, large, usually yellow or purple funnel-shaped flowers.
- Allamanda cathartica — The scientific name of the most well-known species in the genus Allamanda, a vigorous tropical climbing plant popularly known as the 'golden trumpet' or 'common allamanda'. It is famous for its large, waxy yellow flowers up to 12 cm in diameter and is heavily used in tropical landscaping; all parts of the plant are toxic and possess strong purgative properties, from which the specific epithet 'cathartica' originates.
- Allamanda neriifolia — The scientific name of a tropical plant species in the family Apocynaceae, partially synonymous with Allamanda schottii, popularly known as the 'bush allamanda' or 'dwarf golden trumpet'. Unlike other climbing vines of the same genus, it grows as a compact, well-branched shrub, featuring elongated leaves similar to those of the oleander (Nerium oleander) and bright yellow funnel-shaped flowers, followed by spiny and highly decorative fruit capsules.
- Allamanda violacea — The scientific name of a tropical climbing plant species in the family Apocynaceae, synonymous with Allamanda blanchetii, prized for its distinctive violet-pink or purple funnel-shaped flowers. Native to Brazil, this vigorous vine is distinguished by its slightly hairy (pubescent) stems and leaves, and is heavily used to decorate fences, pergolas, and arches in warm climate zones.
- Amsonia — A taxonomic genus of perennial herbaceous plants within the Apocynaceae family, primarily native to North America and East Asia, popularly known as bluestars; these plants are valued in horticulture and garden design due to their characteristic star-shaped light blue or azure flowers, high structural drought resistance, and the intense yellow color that the foliage assumes during the autumn season.
- Amsonia angustifolia — The scientific name of a perennial herbaceous plant species in the genus Amsonia, native to the south-central United States; it is structurally characterized by extremely narrow, linear leaves resembling conifer needles and clusters of star-shaped, pale blue flowers. It is valued in horticulture for its exceptional drought resistance and the intense golden color its foliage assumes in autumn.
- Amsonia tabernaemontana — The type species of perennial plant in the genus Amsonia, native to moist woodlands and meadows of North America; it is structurally distinguished by lanceolate leaves similar to willow leaves and dense clusters of soft, light blue star-shaped flowers. It is widely used in landscape design due to its high adaptability to varying light and soil types, as well as its resistance to pests.
- Apocynaceae — A family of higher dicotyledonous plants, often tropical or subtropical, characterized by the presence of a white latex, regular hermaphrodite flowers, and follicle-type fruits; a plant belonging to this family. Many species possess high pharmacological importance due to their rich content of alkaloids and cardiotonic glycosides, while some are used ornamentally.
- Apocynum — A genus of perennial herbaceous plants in the family Apocynaceae, native to temperate regions of the Northern Hemisphere, characterized by erect stems secreting a whitish latex and small bell-shaped flowers. The genus includes species recognized for high toxicity caused by cardiotonic glycosides, as well as for strong textile fibers historically extracted from the bark.
- Apocynum androsaemifolium — A species of perennial herbaceous plant in the genus Apocynum, remarkable for its pale pink, fragrant, bell-shaped flowers grouped in terminal cymes; commonly known as spreading dogbane. All parts of the plant are highly toxic due to the presence of apocynin and cardiac glycosides, being studied in traditional medicine and biochemistry.
- Apocynum venetum — A species of perennial herbaceous plant in the family Apocynaceae, native to temperate regions of Eurasia, commonly known as Venetian dogbane or luobuma. It is recognized in traditional Chinese medicine and phytotherapy due to its leaves rich in flavonoids and bioactive compounds used to regulate blood pressure and reduce anxiety, while also featuring stalks that provide strong industrial textile fibers.
- Asclepias — A genus of herbaceous perennial plants in the family Apocynaceae (subfamily Asclepiadoideae), popularly known as milkweeds. This taxon comprises over 140 species primarily native to the Americas, structurally remarkable for their complex flowers, toxic latex rich in cardenolides, and an essential ecological role as the exclusive food source for Monarch butterfly caterpillars.
- Swamp milkweed — The scientific name of a perennial herbaceous plant in the Apocynaceae family, native to North America, commonly known as swamp milkweed. It is structurally characterized by erect stems, toxic milky sap, and dense, fragrant, pink-to-purple umbel inflorescences that secrete large amounts of nectar, serving as an essential food source and host plant for the Monarch butterfly.
- Common milkweed — The scientific name of an invasive perennial plant in the Apocynaceae family, native to eastern North America, commonly known as common milkweed. The plant features thick stems, large elliptical leaves, and spherical inflorescences with intensely fragrant pinkish-cream flowers. Due to its rapid spread via underground rhizomes, the species is considered a problematic weed in European agricultural fields.
- Butterfly weed — A species of herbaceous perennial plant native to North America, belonging to the Apocynaceae family, recognized for its dense inflorescences of intense orange or yellow color. It is popularly known as 'butterfly weed' because it attracts pollinators, especially Monarch butterflies, and its tuberous root was historically used in traditional medicine to treat respiratory ailments due to its expectorant properties.
