DETAILS

Care Instructions
Sea Holly is relatively easy to care for. It thrives in full sun and requires well-drained soil. The plant prefers moderate temperatures and can tolerate dry conditions. It does not require frequent watering and can withstand periods of drought. Humidity levels should be moderate, and the plant is best suited for outdoor growth.
Soil
Sea Holly prefers sandy soil with excellent drainage. It can tolerate poor, nutrient-deficient soils and does not require rich, fertile soil. The plant is well-suited to coastal environments where the soil is sandy and well-drained.
Fertilizer
Sea Holly does not require regular fertilization. If desired, a light application of a balanced fertilizer can be applied in the spring to support new growth, but it is generally not necessary.
Repotting
Repotting is not typically required for Sea Holly, as it is best grown directly in the ground. However, if grown in a container, repotting can be done in the spring when the plant is actively growing. Use a well-draining sandy soil mix and ensure the new container has adequate drainage.
Propagation
Sea Holly can be propagated by seed or division. Seeds can be sown in the spring, while division is best done in the early spring or fall. When dividing, ensure each section has a healthy root system and replant immediately in well-drained soil.
Pruning
Pruning is not necessary for Sea Holly. However, dead or damaged foliage can be removed in the spring to encourage new growth. The plant's natural form is attractive and does not require shaping.
Toxicity
Sea Holly is not known to be toxic to pets or humans. It is generally considered safe to grow in gardens where pets and children may be present.
Additional
Sea Holly is an excellent choice for coastal gardens and can be used as a striking focal point in xeriscapes or rock gardens. Its unique appearance and low maintenance requirements make it a popular choice for gardeners looking for a hardy, drought-tolerant plant.
