Cultivation and History

Sea thrift, native to seaside regions in coastal Britain, northern Europe, and the North American Pacific Coast, is known for its striking appearance and ability to thrive in harsh conditions. Its green, grass-like foliage and colorful clusters of flowers make it a popular choice for gardens along the coast.

Propagation

There are several methods to propagate sea thrift, including from seeds, basal cuttings, divisions, and nursery transplants. Each method has its own advantages and challenges, but with the right approach, you can easily propagate sea thrift in your garden.

From Seed: Collect seeds from the species plant and sow them directly outdoors in the spring or start them indoors for an early start.
From Basal Stem Cuttings: Take basal cuttings in spring or summer to propagate new plants.
By Division: Divide existing clumps before spring bloom or in early fall to create new plants.
Transplanting: After all danger of frost has passed, transplant seedlings or nursery starts into the garden or containers.

How to Grow Sea Thrift

Growing sea thrift is relatively straightforward, provided you meet its basic requirements. Choose a sunny location with well-draining soil, and avoid overwatering and overly fertile conditions. With the right care, sea thrift can thrive and bloom beautifully in your outdoor space.

Growing Tips

Use nutrient-poor, well-draining soil.
Avoid amending the soil with organic matter or fertilizer.
Provide sufficient sunlight and moderate watering.
Keep the soil moist during establishment but avoid waterlogged conditions.

Pruning and Maintenance

To ensure healthy growth and longevity of your sea thrift, occasional pruning and maintenance are essential. Divide clumps, remove dead foliage, and deadhead spent flower stems to promote continued blooming. By staying on top of maintenance tasks, you can enjoy vibrant sea thrift in your garden year after year.

Cultivars to Select

While the species plant of sea thrift is a popular choice, there are also cultivated varieties available for home gardeners. From ‘Alba’ with white flowers to ‘Splendens’ with rose-pink blooms, these cultivars add diversity and color to your garden. Differentiate between the species plant and cultivars to ensure successful propagation.

Managing Pests and Disease

Although sea thrift is relatively resistant to pests and diseases, it’s important to monitor for common issues like leafhoppers, slugs, and fungal infections. Treat infestations promptly with appropriate methods to protect your plants and maintain their health and vigor.
