Lomandra ‘Seascape’ is a popular choice for gardeners due to its resilience and visual appeal. This grass-like perennial offers a graceful form and adapts well to various conditions, making it ideal for low-maintenance landscaping.
Understanding Lomandra Seascape
Lomandra ‘Seascape’ is a cultivar of Lomandra confertifolia spp. rubiginosa, originating from Australia. This evergreen perennial features fine, steel-blue to blue-grey foliage with a distinctive weeping habit, forming compact, mounding clumps. It typically reaches a height of 12-24 inches (30-61 cm) and spreads 18-36 inches (46-91 cm) wide. The plant produces small, fragrant yellow flowers on spikes during the summer months, adding a subtle aromatic scent to the garden.
It is highly valued for its drought tolerance and thrives in various well-drained soil conditions. Lomandra ‘Seascape’ also exhibits resistance to common issues like root rot.
Caring for Lomandra Seascape
Planting Lomandra ‘Seascape’ is best undertaken when temperatures are moderate, ideally in spring or autumn, to allow for establishment before extreme weather. A well-draining soil is important for this plant, as it tolerates a variety of soil types but struggles in heavy, poorly drained clay. If your soil is heavy clay, consider amending it with gypsum or planting in a raised mound to improve drainage. Spacing plants 12-18 inches apart will allow for their mature spread and prevent overcrowding.
Lomandra ‘Seascape’ thrives in full sun to partial shade. Once established, it requires infrequent watering. During the establishment phase, however, regular watering is important, especially in dry or hot conditions, usually once a week. After a few years, watering can be reduced to every four to six weeks in dry weather, though more frequent watering (every two to four weeks) can lead to lusher foliage.
Pruning is generally minimal for Lomandra ‘Seascape’ as it maintains a tidy, evergreen form. If foliage becomes untidy or older leaves are smothered by new growth, a hard pruning in late spring can rejuvenate the plant. You can cut back hard to within a few inches of the base, and new growth will emerge. Fertilization is typically not a requirement for mature plants, though a low-phosphorus native fertilizer can be applied in early spring or late summer if desired. Lomandra ‘Seascape’ is generally resistant to most pests and diseases.
Landscape Uses for Lomandra Seascape
Lomandra ‘Seascape’ offers diverse applications in landscape design. Its clumping, weeping habit and blue-grey foliage make it an excellent choice for mass planting, creating a uniform groundcover or adding textural interest.
The plant is effective for erosion control on slopes, thanks to its fibrous root system that helps stabilize soil. Its tidy form lends itself well to defining borders, creating crisp edges along pathways, or softening the appearance of retaining walls. Lomandra ‘Seascape’ is suitable for container gardening, where its weeping foliage can gracefully spill over the pot’s edges. It is also a fitting selection for water-wise gardens and coastal environments.
