Molucella Lavevis, commonly known as Bells of Ireland, is a striking annual that adds height, texture, and an elegant green hue to gardens and floral arrangements. Known for its tall, sturdy stems covered in bell-shaped calyces, this plant is a florist’s favorite for cut flower arrangements. Whether you are growing them for personal enjoyment or for market bouquets, Bells of Ireland will bring a unique charm to your garden.
Why Grow Bells of Ireland?
Bells of Ireland are not only beautiful but also highly versatile. Their tall spires—reaching up to 24–36 inches—make them excellent for the back of flower beds or as an eye-catching vertical element in arrangements. The vibrant green color pairs wonderfully with both bold and pastel blooms. They also have a long vase life, making them ideal for fresh and dried floral designs.
When and Where to Plant
Bells of Ireland thrive in full sun but can tolerate partial shade, especially in hotter climates. They prefer well-drained soil and cooler temperatures for optimal germination. In colder climates, sow seeds indoors 8–10 weeks before your last frost date. In milder climates, you can direct sow outdoors in early spring.
Pro Tip: Bells of Ireland seeds have a natural dormancy. To improve germination, refrigerate seeds for 1–2 weeks before planting.
How to Sow the Seeds
-
Indoor Sowing:
-
Fill seed trays with a quality seed-starting mix.
-
Press seeds lightly into the surface without covering them completely, as they need light to germinate.
-
Mist the soil to keep it consistently moist.
-
Maintain a temperature of around 65–70°F for best results. Germination can take 14–21 days.

-
Outdoor Sowing:
-
Prepare a fine seedbed in a sunny location.
-
Sow seeds thinly and press them into the soil surface.
-
Keep the soil moist until seedlings emerge.

Care and Maintenance
Once your seedlings are established, thin them to 12–15 inches apart. Bells of Ireland prefer consistent moisture but dislike soggy soil. Water at the base to prevent leaf diseases, and apply a balanced, slow-release fertilizer at planting time to encourage strong growth.
For taller stems, consider staking plants to prevent them from bending in the wind. Removing spent blooms will encourage continuous flowering.
Harvesting for Cut Flowers
The best time to cut Bells of Ireland is when the calyces are fully open and vibrant. Use sharp scissors or garden snips to make clean cuts early in the morning. Strip off the lower leaves before placing stems in water. With proper care, they can last up to two weeks in a vase.
For dried arrangements, hang stems upside down in a cool, dark, and well-ventilated area until completely dry.
