Description
Allium ‘Purple Sensation’ is a popular bulbous perennial that is prized for its large, spherical, deep purple flower heads and attractive foliage. This cultivar is also known as the ornamental onion ‘Purple Sensation’. At the top of each stem, the plant produces a large, round flower head that is made up of hundreds of small, star-shaped, purple flowers. The flower heads are long-lasting and can be used for cut flower arrangements.’Purple Sensation’ is an excellent choice for borders, rock gardens, and container plantings. It can also be mass-planted for a stunning effect or used as a specimen plant in mixed borders. The plant is low-maintenance, easy to grow, and can be propagated by division in the fall. It is also relatively pest and disease-resistant. One thing to note is that after the plant flowers, the foliage may turn yellow and begin to wither. It’s best to leave the foliage in place until it has completely died back, as this will allow the bulb to store energy for the next growing season.
