The genus Aquilegia, or Watershed (Aquilegia), includes about 100 herbaceous perennial species that are grown as annuals or biennials. Lower leaves are long-stemmed, twice - and thrice-striated glabrous; stem-trifoliate sessile. Differently colored flowers consist of 5 sepals and 5 petals, bent back and having elegant "extensions", the so-called spurs. They bloom from May to July. Species for stony gardens with a height of 10-30 cm came from the Alps and Pyrenees, others-from the Far East.
Alpine Aquilegia (Aquilegia alpina) from Switzerland with blue and white flowers; Aquilegia Bertoloni (A. bertolonii) from Italy with purple-blue flowers; Aquilegia discolor (A. discolor) from Spain with pale blue or white flowers; Aquilegia fan-shaped (A. flabellata) from Japan with transitions from white to lilac-blue; Aquilegia rocky (A. scopulorum) with the Rocky mountains painted in shades from pale lavender to dark purple. The height of species for borders is up to 1 m, with large flowers native to North America. The exception is the common Aquilegia (A. vulgaris), which is the only species of European origin. Hybrids with white, red, blue and yellow flowers were artificially bred from it. The catchment area is light blue (A. caerulea) from the USA white flowers with a transition to blue or yellow. Aquilegia canadensis (a. canadensis) has yellow flowers with red spurs.
