Moluccella laevis, commonly known as Shellflower or Bells of Ireland, is a fast-growing annual herb native to Turkey, Syria, and the Caucasus region. It is typically found in open fields and on grassy slopes, adapting well to a range of ecological conditions within its native range. This plant reaches a height of 2-3 feet and a width of 1-2 feet, featuring square stems that are characteristic of the mint family to which it belongs. Shellflower is notable for its unique inflorescences, which consist of apple-green calyces that form a bell-like structure around tiny white flowers, blooming in the summer and fall. The flowers are not particularly showy, but the calyces are quite striking and provide a lasting visual interest.

Shellflower is valued for its distinctive flower spikes that add a vertical element and a touch of whimsy to garden beds and borders. It is also popular in cut flower arrangements, both fresh and dried, due to the long-lasting nature of the calyces. In cultivation, it thrives in full sun and requires medium amounts of water, performing best in well-drained soils. It is a self-seeding plant, which can be beneficial for naturalizing in suitable climates but may require management to prevent unwanted spread. While it is adaptable to various soil types, it does not fare well in hot, humid climates and may struggle in such conditions. Gardeners should be aware that in some areas, it can become invasive if not managed properly.CC BY-SA 4.0
