- Aquilegia — A genus of herbaceous perennial plants in the family Ranunculaceae, popularly known as 'columbine'; these structural plants are recognized by their spectacular, rarely shaped flowers equipped with long nectar spurs, being widely utilized in decorative horticulture and studied in evolutionary biology.
- Aquilegia alpina — A species of perennial plants in the genus Aquilegia, native to the alpine meadows and rocky areas of the Alps; this structural plant is recognized by its large, intense-blue or violet flowers, being protected in spontaneous flora and highly appreciated as an ornamental plant in alpine gardens due to its resistance to low temperatures.
- Aquilegia caerulea — A species of herbaceous perennial plants in the genus Aquilegia, native to the Rocky Mountains of North America; this structural plant features large, spectacular, typically bicolor flowers (with white petals and blue sepals), being declared the official state flower of Colorado and frequently used as an ecological symbol and luxury decorative plant.
- Aquilegia chrysantha — A species of herbaceous perennial plants in the genus Aquilegia, native to the southwestern United States and northern Mexico; this structural plant stands out for its large, intense golden-yellow flowers, equipped with exceptionally long and slender nectar spurs, being highly heat-tolerant compared to other alpine species.
- Aquilegia glandulosa — A species of herbaceous perennial plants in the genus Aquilegia, native to the alpine and subalpine zones of Siberia, Mongolia, and China; this structural plant is characterized by fine glandular hairs on its stems and leaves, as well as large, bicolor flowers with intense-blue sepals and white inner petals.
- Aquilegia sibirica — A species of herbaceous perennial plants in the genus Aquilegia, native to the coniferous forests, glades, and alpine meadows of Siberia, Mongolia, and Central Asia; this structural plant stands out for its spectacular bicolor flowers, usually featuring large intense blue-violet sepals and white inner petals, being extremely hardy in severe subarctic climates.
- Aquilegia skinneri — A species of herbaceous perennial plants in the genus Aquilegia, native to the mountainous zones and humid canyons of northwestern Mexico (Sierra Madre Occidental); this structural plant is famous for its spectacular tricolor flowers, featuring greenish-yellow sepals, yellow inner petals, and exceptionally long, bright orange-red nectar spurs.
- Aquilegia transsilvanica — A species of herbaceous perennial plants in the genus Aquilegia, endemic to the mountain chain of the Romanian Carpathians (especially in the high limestone areas of Bucegi, Piatra Craiului, and Făgăraș); this structural plant stands out for its large, intense blue-violet flowers, being declared a monument of nature and strictly protected in alpine reserves due to its restrictive geographical range.
- Aquilegia vulgaris — The type species of herbaceous perennial plants in the genus Aquilegia, native to Europe and widely utilized as an ornamental plant in gardens; this structural plant possesses spectacular flowers with a diverse chromatic palette (ranging from blue, violet, and pink to white), being popularly known as 'columbine' and intensely studied due to its biochemical and genetic properties.
