Step-by-step planting
Growing Bells of Ireland from seed takes some planning, but gardeners who give it the right conditions are rewarded with tall, graceful spikes that earn their place in both the garden and the vase.
-
1
Cold Stratify Your Seeds
Place Bells of Ireland seeds in a damp paper towel inside a sealed bag and refrigerate them for 4 to 5 weeks before sowing, as this cold stratification process mimics winter conditions and significantly improves germination results.
-
2
Choose the Right Timing
Start seeds indoors 8 to 10 weeks before your last frost date, or direct sow outdoors in early spring as soon as the soil can be worked, since Moluccella laevis thrives in cool soil temperatures between 55 and 65 degrees Fahrenheit.
-
3
Sow at the Surface
Press seeds lightly onto the surface of moist seed-starting mix and do not cover them, because Bells of Ireland seeds need light to germinate and burying them will work against you.
-
4
Keep Moisture Consistent
Mist the surface regularly to maintain even moisture without waterlogging the medium, as the seeds are small and a drying-out period during germination can set the process back considerably.
-
5
Transplant with Care
Harden off indoor seedlings over 7 to 10 days before moving them to the garden, and transplant on a cloudy day or in the evening since Bells of Ireland has somewhat sensitive roots that resent rough handling.
-
6
Plant in Full Sun
Choose a spot with full sun and well-drained soil, spacing plants about 12 inches apart so air can circulate freely around the stems, which helps prevent the fungal issues that can develop in humid conditions.
-
7
Support Tall Stems
Stake plants or grow them alongside other tall flowers for support once they reach 18 inches or more, as the spikes can top 3 feet and will flop in wind or heavy rain without something to lean on.

Frequently asked
Questions about Bells of Ireland Seeds – Moluccella laevis
Do Bells of Ireland seeds need cold stratification?
Cold stratification is not absolutely required, but it makes a meaningful difference in how reliably Bells of Ireland seeds germinate. Chilling the seeds for 4 to 5 weeks in a moist environment before sowing mimics the natural winter conditions the plant experiences in its native habitat. Skipping this step often results in slower, spottier germination, so it is worth the extra time if you can plan ahead.
How long do Bells of Ireland take to germinate?
Germination timing for Bells of Ireland seeds varies depending on soil temperature, moisture, seed freshness, and whether cold stratification was used. Under good conditions with stratified seeds and soil temperatures around 55 to 65 degrees Fahrenheit, you might see sprouts in 14 to 25 days. Warmer or drier conditions can delay things further, so do not give up on a tray too quickly.
Can I direct sow Bells of Ireland seeds?
Yes, direct sowing works well in climates with a cool, moist spring. Sow seeds directly into prepared garden beds as early as the soil can be worked, pressing them onto the surface rather than covering them since they need light to sprout. In warmer climates where spring heats up quickly, starting seeds indoors gives you a better window to establish plants before the heat sets in.
Do Bells of Ireland grow well in containers?
Bells of Ireland can be grown in containers, but it is not the easiest fit given that the plants can reach 2 to 3 feet tall and need good root depth to support those stems. If you go this route, choose a deep pot of at least 12 inches and a well-draining mix, and be prepared to stake the plants. They tend to perform much more vigorously in open garden beds where roots are not restricted.
When should I harvest Bells of Ireland for arrangements?
For fresh cut flower use, harvest stems when the lower two-thirds of the spike have fully formed calyces and the top portion is still developing. Cut in the early morning, strip the lower leaves, and place stems in cool water immediately. For Bells of Ireland dried flower use, allow stems to mature fully on the plant and then hang them upside down in a dark, dry, well-ventilated space for two to three weeks.
Why won't my Bells of Ireland seeds germinate?
The most common reasons are soil that is too warm, seeds that were buried rather than surface sown, or inconsistent moisture during the germination period. Moluccella laevis germinates in cool conditions, and temperatures above 70 degrees Fahrenheit can significantly reduce success. If you have tried before without luck, refrigerating the seeds for a few weeks before your next attempt and sowing in a cooler spot often makes a noticeable difference.
Are Bells of Ireland toxic to pets?
Bells of Ireland is not widely listed as a toxic plant for dogs or cats, but the fine hairs on the plant can cause mild skin or mouth irritation if chewed. As with any ornamental plant, it is a good idea to keep pets from making a habit of nibbling on it. If you have a pet with a tendency to chew garden plants, check with your veterinarian for the most current guidance specific to your animal.
