Flowers create color and texture in the garden. Some flowers are more unusual than others and flowers with unusual shapes always get attention. Some of the flowers with the most unusual shapes are flowers that are shaped like balls or spheres. In most cases the flowers are actually a round-shaped cluster of many blooms of one color that give the appearance of a ball.
Ornamental onions produce flowers that are globe shaped. There are several different varieties with different sized ball-shaped flowers. Common varieties available are the Drumstick Allium (Allium sphaerocephalon) with quarter-sized flowers, the Allium giganteum with softball sized flowers and the Globemaster allium with ball-shaped flowers the size of vollyeballs. All varieties prefer well-drained soil and can naturalize if grown in the right conditions. Ornamental onion flowers make long-lasting and interesting cut flowers.
