Compare these two plants side by side — care needs, key differences, and which is right for your home.
Bells of Ireland
Moluccella laevis
Bells of Ireland is an annual flowering plant known for its tall spikes of vibrant green, bell-shaped calyces (modified leaves) that surround tiny, inconspicuous white flowers. It typically grows to a height of 2-3 feet. While it can be grown indoors, it's primarily an outdoor plant, often cultivated in gardens for its unique architectural form and long-lasting cut flowers. People grow it for its ornamental value, particularly in floral arrangements, where its bright green color adds a striking contrast.
Coriander
Coriandrum sativum
Coriandrum sativum, commonly known as coriander or cilantro, is an annual herb growing to about 50 cm (20 inches) tall. All parts of the plant are edible, but the fresh leaves and the dried seeds are the parts most traditionally used in cooking. It has a slender stalk and lacy leaves. It is primarily grown for culinary purposes, adding a distinctive flavor to dishes. While it can be grown indoors, it requires very bright light and consistent moisture to thrive, making it more challenging than many other herbs.
