The oddly protruding stamens of pincushion flower, Scabiosa columbaria, are ideal for bees collecting pollen. To us, they resemble pins stuck into the somewhat flat surface of the composite (daisy like) flowers. To bees, they are a flea market (or bee market) of pollen. Bees easily stroll the two inch wide flowers to peruse the merchandise on display. 

The pale lavender, blue, pink or white flowers on limber stems are good cut flowers. The grayish foliage is deeply lobed and nicely textured. Mature plants can be two feet tall and broad. Bloom begins by summer and continued until frost if fading flowers get plucked. Although perennial in mild climates, pincushion flower is more often grown as an annual.
