Caucasian pincushion flower

Description

Scabiosa caucasica, the Caucasian pincushion flower, pincushion-flower or Caucasian scabious, is a species of flowering plant in the family Caprifoliaceae, native to the Caucasus, north eastern Turkey, and northern Iran. Growing to 60 cm (24 in) tall and broad, it is a clump-forming perennial with divided leaves. Pincushion-shaped buds, borne on erect stems, open to pale blue or lavender flower heads, 8 cm (3 in) in diameter, from late summer through to autumn. The plant is highly attractive to bees and other pollinating insects. Saxifraga is the largest genus in the family Saxifragaceae, containing about 440 species of holarctic perennial plants, known as saxifrages or rockfoils. The Latin word saxifraga means literally "stone-breaker", from Latin saxum ("rock" or "stone") + frangere ("to break"). It is usually thought to indicate a medicinal use for treatment of urinary calculi (known as kidney or bladder stones), rather than breaking rocks apart. Most saxifrages are small perennial, biennial (e.g. S. adscendens) or annual (e.g. S. tridactylites) herbaceous plants whose basal or cauline leaves grow close to the ground, often in a rosette. The leaves typically have a more or less incised margin; they may be succulent, needle-like and/or hairy, reducing evaporation. The inflorescence or single flower clusters rise above the main plant body on naked stalks. The small actinomorphic hermaphrodite flowers have five petals and sepals and are usually white, but red to yellow in some species. Stamens, usually 10, rarely 8, insert at the junction of the floral tube and ovary wall, with filaments subulate or clavate. As in other primitive eudicots, some of the 5 or 10 stamens may appear petal-like and it lives in tundral ecosystems. A genus of about 440 species. The former monotypic genus Saxifragella has been submersed within Saxifraga, the largest genus in Saxifragaceae, as Saxifraga bicuspidata. Also the genus Saxifragopsis (strawberry saxifrage) was previously included in Saxifraga.
