How to Grow and Care for Sea Daffodil
Plant Overview
The Sea Daffodil (Pancratium maritimum) is a stunning perennial plant native to the Mediterranean region. Known for its striking white flowers that bloom in summer, this plant thrives in sandy coastal areas. The Sea Daffodil typically grows to a height of 12 to 18 inches and features long, strap-like leaves that can reach up to 24 inches in length. Its bulbous roots store water, making it well-adapted to dry environments.
Optimal Growing Conditions
Light Requirements
Sea Daffodils flourish in full sun. Aim for at least 6-8 hours of direct sunlight each day to promote healthy growth and flowering.
Temperature
This plant prefers warm temperatures typical of Mediterranean climates. Ideally, it thrives in temperatures between 60°F to 80°F (15°C to 27°C). It can tolerate short periods of cooler temperatures but is not frost-resistant.
Soil
Well-draining sandy or loamy soil is essential for the Sea Daffodil. It can tolerate poor soil conditions but performs best in slightly alkaline to neutral pH levels (6.0 to 7.5). Adding organic matter can improve soil quality.
Watering
Water the Sea Daffodil deeply but infrequently. Allow the soil to dry out between waterings to prevent rot. During the growing season, water regularly, but reduce watering in the dormant winter months.
Humidity Requirements
Sea Daffodils prefer moderate humidity levels. They are well-suited for coastal areas where humidity is naturally higher. However, they can adapt to drier conditions as long as their watering needs are met.
Seasonal Care Tips
Spring Care
In spring, begin watering regularly as the plant emerges from dormancy. Fertilize with a balanced, slow-release fertilizer to encourage robust growth and flowering. Check for any signs of pests or disease.

Summer Care
During the summer months, ensure the Sea Daffodil receives ample sunlight and water. Deadhead spent flowers to encourage further blooming and maintain the plant’s appearance. Be vigilant for pests such as aphids or spider mites.
Fall Care
As temperatures begin to drop in fall, gradually reduce watering. Allow the foliage to die back naturally, which helps the plant conserve energy for the next growing season. This is also a good time to apply a light layer of mulch to protect the roots.
Winter Care
In winter, protect the Sea Daffodil from frost by covering it with mulch or moving potted plants indoors. Water sparingly, just enough to keep the soil from completely drying out. The plant will enter dormancy and should not be fertilized during this period.
Common Issues & Solutions
Pests
Common pests include aphids and spider mites. Regularly inspect the leaves and stems, and treat infestations with insecticidal soap or neem oil. Ensure good air circulation around the plant to minimize pest problems.
Diseases
Root rot is a significant concern, especially if the plant is overwatered. Ensure proper drainage and avoid letting the plant sit in water. If you notice yellowing leaves, this may indicate overwatering or nutrient deficiency. Adjust your watering schedule and consider fertilizing.
Yellow Leaves
Yellow leaves can signal several issues, including nutrient deficiency or overwatering. Check the soil moisture levels and adjust your watering schedule. If the soil is too compacted, consider repotting or amending the soil with organic matter.

Propagation Guide
Propagating Sea Daffodils can be done through bulb division or seed sowing. Here’s a step-by-step guide for each method:
Bulb Division
- Wait until late summer or early fall when the plant is dormant.
- Carefully dig up the bulbs, taking care not to damage them.
- Separate the bulbs, ensuring each has roots and scales attached.
- Replant the bulbs immediately in well-draining soil, spacing them about 12 inches apart.
- Water lightly and place in a sunny location.
Seed Sowing
- Collect seeds from mature flowers in late summer.
- Plant seeds in a seed tray filled with a well-draining potting mix.
- Water gently and cover with a thin layer of soil.
- Place the tray in a warm, sunny location and keep the soil moist.
- Once seedlings are established and have a few sets of leaves, transplant them into individual pots.
