The flowers grow on long, grey-green stems that can extend over one meter in height, and each flower is comprised of small, narrow, and jagged petals that cluster around a central disc. The flowers have a frilly, delicate appearance, and the petals are soft and crisp.


Wild varieties of Bachelor’s Button flowers were primarily a cobalt blue, but with increased cultivation, the flowers now appear in shades of blue, purple, crimson, pink, and white. Bachelor’s Button flowers emit a faint aroma, and the petals are edible, containing a subtly vegetal, sweet, and peppery taste with cucumber and clove nuances.


Bachelor’s Button flowers are native to Europe and Western Asia and have been growing wild since ancient times.
