Bells of Ireland

Bells of Ireland (Moluccella laevis) is an annual herbaceous plant belonging to the Lamiaceae family, native not to Ireland as the common name suggests, but to the regions between Turkey, Syria and the Caucasus. Cultivated since 1570, this unusual plant was once widely grown in cottage gardens, where in folk tradition it represented a symbol of good luck. Its striking appearance, dominated by a bright apple-green color, makes it one of the most eye-catching and recognizable plants among cut flowers.

The Bells of Ireland Plant

This is an upright, branching plant that can reach a meter in height, characterized by rounded, light green leaves and sturdy square-sectioned stems, typical of the Lamiaceae family. The truly distinctive feature of the plant isn't the small, almost imperceptible white flowers, but rather the large apple-green bell-shaped calyces that surround them, densely arranged along tall vertical spikes. It's precisely these persistent, almost papery-textured calyces that give Bells of Ireland its distinctive, sought-after look, much appreciated in both fresh and dried bouquets.

How to Sow Bells of Ireland

Sowing Bells of Ireland requires a bit more care than other annuals, since the seeds need a period of cold to germinate reliably: it's advisable to store them in the refrigerator or even the freezer for one to two weeks before sowing, mimicking the natural cold stratification period. Sow directly in the ground in spring, once the soil reaches 50-60°F (10-16°C), or in individual pots six to eight weeks before transplanting, since the plant has a taproot that doesn't tolerate later transplanting well. The seeds should only be lightly pressed onto the soil surface without covering them, as they need light to germinate, keeping the substrate consistently moist.

How to Grow Bells of Ireland

Bells of Ireland prefers full sun or light partial shade, and adapts well to any garden soil as long as it's well-draining and moderately fertile. Watering should be provided regularly, keeping the soil evenly moist without creating standing water, which is particularly harmful to the root system. Given the height it can reach, especially under vigorous growing conditions, it can be helpful to provide a stake or light support to prevent the stems from bending under the weight of the flowering spikes, especially in windy conditions.

An occasional application of balanced fertilizer during the growth phase can encourage more vigorous development, though this plant isn't particularly demanding nutritionally. It pairs beautifully with other border annuals and perennials, such as foxglove, bellflower, columbine, love-in-a-mist and cornflower, creating well-balanced color combinations.

Growing Tips for Bells of Ireland

This plant's foliage can feel slightly prickly to the touch: when handling it for harvesting or arranging, it's advisable to wear gardening gloves to avoid irritating the skin. For harvesting as a cut flower, cut the stems once the spikes are well formed but still bright green, removing the lower leaves to better showcase the characteristic bells. Being a plant that tends to self-seed easily in mild climates, it may reappear spontaneously the following year in the same spot in the garden.

Diseases and Pests of Bells of Ireland

Bells of Ireland is generally a hardy plant, not particularly prone to significant diseases or pests, a trait that makes it suitable even for those with little gardening experience. The one important precaution concerns soil drainage: excess standing moisture can encourage root rot, especially in the early growth stages of young seedlings. Adequate spacing between plants, combined with well-draining soil, is generally enough to keep it in excellent health for the whole season.

Uses and Curiosities of Bells of Ireland

Thanks to its characteristic apple-green calyces, which retain their shape and color even once dried, gradually turning a straw color, Bells of Ireland has always been one of florists' favorite plants for both fresh and long-lasting dried arrangements. Its tall vertical spikes provide excellent structural contrast to softer, rounder flowers in any bouquet. A botanical curiosity: despite the common name "Bells of Ireland," this plant has no historical or geographical connection to Ireland, but likely owes its name to its bright green color, so reminiscent of the Irish landscape, as well as to its traditional association with St. Patrick's Day in the English-speaking world.
