All About Bells of Ireland
Bells of Ireland, scientifically known as Moluccella laevis, are annual flowering plants native to Turkey, Syria, and the Caucasus. Despite their common name, they have no special link to Ireland, but they are associated with the country due to their vivid green color, reminiscent of the Emerald Isle.
These unique plants grow to roughly 2-3 feet tall, bearing fascinating bell-shaped calyxes that enclose the small, fragrant, white flowers. The “bells” or calyxes are the main attraction, showing a striking bright green that tends to fade as the summer progresses.
Bells of Ireland are relatively easy to grow, and they thrive in full sun and well-drained soil. They are not particularly fussy about soil type and can handle both acidic and alkaline conditions. They are hardy to USDA zones 2-11 and are often grown as annuals.
Seeds can be sown directly into the ground in early spring, but as they need light to germinate, they should not be covered with soil. Seedlings should be thinned to a spacing of about 12 inches to give each plant enough room to develop.
These plants have a long blooming period, from late spring through summer, and they make excellent cut flowers, which can also be dried for use in winter arrangements.
Despite their delicate appearance, Bells of Ireland are quite hardy, and they are resistant to many common plant diseases. However, they can occasionally suffer from problems such as mildew and rust, so regular monitoring is essential.
With their unique charm and easy-care nature, Bells of Ireland are a great addition to any garden, offering a touch of whimsy and a dash of vibrant green color.
Varieties of Bells of Ireland
While the most common variety of Bells of Ireland that we see in gardens is the traditional Moluccella laevis, this plant does have some interesting varieties worth exploring. Let’s take a look at some of them.
Moluccella Spinosa
The Moluccella Spinosa, often referred to as the Spiny Bells of Ireland, is a historic variety that was first described in the 16th century. It features prickly, spiky green flowers encased in more spiny calyxes. Despite its sharp appearance, it has a delicate, almost sweet scent, similar to fresh green apples. What sets this variety apart is its compact growth habit, which makes it an excellent choice for smaller gardens.
Moluccella Laevis ‘Alba’
This is an unusual variety of Bells of Ireland, prized for its pure white flowers. Moluccella Laevis ‘Alba’ is a white-flowered form of the classic Bells of Ireland.
