Tall spikes of apple-green bells make you stop and notice bells of Ireland (Moluccella laevis). This annual has whorls of bell-shaped bracts and tiny cream-colored flowers in the center of each bell. Its rounded leaves are pale green. Bells of Ireland is a unique bedding plant with its standout, green-only coloring, but it's also a stunning addition to both fresh and dried flower arrangements. It's native to western Asia, Turkey, Syria, and Caucasus, where it grows in fields and on stony slopes.

- Sow seed indoors in early spring or outside in late spring. Germination can be slow. To speed this up, seal seeds in a bag after sowing and leave in a refrigerator for 2 weeks. Then place the seeds in a warm spot (65°F to 70°F). Germination usually starts after 14 to 21 days. Harden off for 10 to 15 days before planting outside when all danger of frost is gone.
Pests and diseases:
- The tall, green spikes add interest to a mixed annual border.
- Some sources say bells of Ireland is deer-resistant.
- Vase life for fresh flowers is 7 to 10 days.
- Flower spikes make interesting dried flowers. To dry them, pick a dry day when flowers are fully open, near their peak of maturity. Remove unnecessary foliage, and gather the stems into bunches. Wrap a rubber band or twine around the end of the stems and attach the bundle to a hook or hanger. Hang upside down in a dry, well-ventilated place for three to five weeks until they're entirely dry. As they dry, the flowers fade to cream or tan.
All in the family:
- The Lamiaceae family consists mostly of herbs or shrubs with aromatic leaves, four-sided stems, and flowers arranged in whorls. Mint (Mentha spp.), Russian sage (Perovskia atriplicifolia), rosemary (Rosmarinus officinalis), coleus (Solenostemon scutellarioides), and sages (Salvia spp.) are related to bells of Ireland.
