• Albanian pasqueflower — A scientific synonymous name for Pulsatilla albana, a perennial herbaceous plant in the family Ranunculaceae, native to alpine and rocky areas of the Caucasus and Iran. The plant is distinguished by the dense, silky hairs covering it completely, deeply divided leaves, and its nodding, bell-shaped flowers colored in shades of cream-yellow, light violet, or purple.
• Baikal anemone — A species of perennial herbaceous plant in the family Ranunculaceae, native to the temperate regions of Eastern Asia, particularly around Lake Baikal in Siberia, as well as Mongolia and northern China. This forest plant develops a slender, creeping rhizome, delicate stems covered with fine hairs, and solitary flowers of an immaculate white, being a specific floristic element of Asian mountain and subalpine forest ecosystems.
• Mount Baldo anemone — A species of perennial herbaceous plant in the family Ranunculaceae, native to the high mountain ranges of southern and central Europe, particularly the Alps. This small alpine plant grows on rocky slopes, screes, and limestone soils, characterized by a branched rhizome, deeply divided leaves, and solitary pure white flowers, often with pinkish-red tinges on the outer side of the sepals.
• Carolina anemone — A species of perennial herbaceous plant in the family Ranunculaceae, native to the central and southeastern regions of the United States. This prairie plant grows on dry, sandy, or calcareous soils, featuring a tuberous rhizome from which delicate stems emerge, each bearing a single solitary flower with numerous petaloid sepals that range from white and pink to light violet, blooming in early spring.
• Poppy anemone — A species of tuberous perennial herbaceous plant in the family Ranunculaceae, native to the Mediterranean region. It is highly valued as an ornamental plant and cut flower due to its large, solitary, cup-shaped flowers, vividly colored in shades of red, blue, purple, or white, often with a white ring at the base and a prominent center with numerous blackish-purple stamens.
• Haller's pasqueflower — A scientific synonymous name for Pulsatilla halleri, a perennial herbaceous plant in the family Ranunculaceae, native to the high mountain regions of Central and Southern Europe (Alps, Carpathians, Balkans). This rare alpine species is remarkable for its dense pubescence, being completely covered in long, silky hairs that protect it from the cold, and for its large, erect, violet cup-shaped flowers that appear in early spring.
• Japanese anemone — A species of perennial herbaceous plant in the family Ranunculaceae, native to central and western China, but naturalized for centuries in Japan. It is highly popular in horticulture as an autumn-blooming ornamental plant, standing out due to its tall stature, large trifoliate leaves, and branched stems bearing numerous spectacular flowers with pink or white sepals and a center of bright yellow stamens.
• Mexican anemone — A species of perennial herbaceous plant in the family Ranunculaceae, native to the mountainous regions and pine-oak forests of Mexico and Central America. This warm-temperate plant develops erect stems, deeply lobed basal leaves, and solitary or clustered flowers with delicate cream-white or slightly greenish sepals, adapted to high-altitude forest ecosystems.
• Eastern pasqueflower — A scientific synonymous name for Pulsatilla patens, a perennial herbaceous plant in the family Ranunculaceae, widely distributed across the cold and temperate regions of Europe, Asia, and North America. It is famous as an early prairie or steppe wildflower, developing densely pubescent stems and large, erect, chalice-shaped flowers colored in shades from pale blue-violet to purple, often opening before the leaves fully emerge.
• Small pasqueflower — A scientific synonymous name for Pulsatilla pratensis, a perennial herbaceous plant in the family Ranunculaceae, native to steppes, dry meadows, and sparse forests of Central and Eastern Europe. The plant is covered in long, silky hairs and is recognized by its characteristic nodding (drooping) flowers, shaped like a narrow bell and colored in a deep, dark violet or almost blackish hue, appearing in early spring.
• Pasqueflower — A scientific synonymous name for Pulsatilla vulgaris, a perennial herbaceous plant in the family Ranunculaceae, native to calcareous grasslands and sunny slopes across Europe. This early spring plant is entirely covered in a dense layer of silky hairs, standing out due to its large, erect or slightly nodding, deep violet bell-shaped flowers, with a striking contrast generated by the bright golden-yellow stamens in the center.
• Riverside anemone — A scientific synonymous name for Eriocapitella rivularis, a perennial herbaceous plant in the family Ranunculaceae, native to a wide range across Asia (Himalayas, India, China, Nepal). This vigorous garden plant prefers stream banks, floodplains, and damp meadows, standing out due to its tall, branched stems that bear numerous immaculate white flowers, whose sepals have a blue-indigo or violet reverse, highlighting the azure stamens in the center.
• Snowdrop anemone — A species of perennial herbaceous plant in the family Ranunculaceae, native to dry grasslands, woodland edges, and sunny clearings of Central and Eastern Europe to Siberia. Commonly known as the snowdrop anemone or wood anemone, this vigorous plant is remarkable for its dense clumps, deeply lobed leaves, and large, solitary or paired pure white flowers with a delicate fragrance and bright yellow central stamens, followed by woolly seed heads.
• Spring pasqueflower — A scientific synonymous name for Pulsatilla vernalis, a perennial herbaceous plant in the family Ranunculaceae, native to mountainous and arctic regions of Europe (Alps, Pyrenees, Scandinavia). Commonly known as the spring pasqueflower, this early alpine species is remarkable for its winter-persistent basal leaves and its solitary, cup-shaped flowers covered on the outside with silky, golden-violet hairs that protect the immaculate white petals within.
• Genus Anemopsis — A monotypic taxonomic genus of perennial herbaceous plants in the family Saururaceae, exclusively represented by the species Anemopsis californica (commonly known as yerba mansa). The plant is native to wet, saline, and alkaline areas of the southwestern United States and northern Mexico, characterized by a unique conical inflorescence surrounded by large white bracts that mimic an anemone flower, and by roots with strong medicinal properties.
