About Sea Grape
A distinctive coastal tree with large, round, leathery leaves that turn red and bronze before dropping, and clusters of grape-like purple fruits that are edible and mildly sweet. Its thick trunk, spreading canopy, and tolerance for salt spray, wind, and sandy soil make it an excellent beachfront and coastal garden tree. The oversized round leaves create bold visual impact in any landscape. Sea Grape belongs to the Polygonaceae family and originates from Tropical Americas — Caribbean, Florida, Central America, and northern South America. Planted in the Philippines as a coastal and ornamental tree..
Sea Grape is becoming popular in Philippine coastal resort landscaping, particularly in Cebu, Palawan, and Batangas beach properties. Its salt tolerance and bold, tropical aesthetic make it ideal for beachfront gardens. The edible fruits can be made into jelly or eaten fresh, though this is not yet common practice in the Philippines. Available at specialty nurseries and larger landscape suppliers. Its wind resistance is a significant advantage in typhoon-prone areas. Some landscape architects use it as a specimen tree in modern tropical garden designs in Metro Manila.
Also known as: Baygrape, Uvas de Playa.

How to Plant Sea Grape in the Philippines
Sea Grape can be propagated through seeds, stem cuttings, air layering. The recommended method is seeds from ripe purple fruits.
Propagation Steps
- Step 1: Collect ripe purple fruits from healthy trees.
- Step 2: Remove the fleshy outer layer and clean the seed.
- Step 3: Plant immediately in well-draining sandy soil mix, 1-2 cm deep.
- Step 4: Keep moist and warm (28-32°C).
- Step 5: Germination takes 2-4 weeks.
- Step 6: Seedlings are slow-growing for the first year; be patient.
Care Guide
Sunlight
Full sun (6-8 hours direct sun; this is a sun-loving coastal species). Position your sea grape where it receives the right amount of light for healthy growth in Philippine conditions.
Water
Low to moderate once established. Very drought-tolerant. Water young trees regularly until roots are deep. Adjust frequency during the Philippine rainy season when humidity is higher and soil stays moist longer.
Temperature & Humidity
Ideal temperature range: 25-35°C (heat-loving; cold-sensitive below 5°C). Tolerates low to high humidity — naturally adapted to coastal wind and salt spray The warm, humid Philippine climate is well-suited for growing sea grape outdoors or indoors.
Fertilizer
Light feeding with balanced slow-release fertilizer (14-14-14) twice a year. Too much fertilizer can produce leggy growth.
Pruning
Prune to shape as desired. Can be maintained as a multi-trunk shrub or trained as a single-trunk tree. Remove lower branches for a cleaner trunk.
Toxicity & Safety
Non-toxic. Fruits are edible and mildly sweet when ripe.
Common Problems & Solutions
Leaf spots or rust patches
Cause: Fungal infections in humid, poorly ventilated conditions
Solution: Ensure good air circulation. Remove affected leaves. Spray with copper-based fungicide if needed.
Slow growth
Cause: Normal for this species, especially when young or in poor soil
Solution: Be patient. Amend soil with compost. Growth rate increases after the first 2-3 years.
Leaf drop
Cause: Natural semi-deciduous behavior; leaves may drop during dry season or stress
Solution: Normal. New leaves emerge quickly. Maintain moderate watering during dry season to reduce leaf drop.
Fruit staining on pavement
Cause: Ripe purple fruits dropping and staining walkways
Solution: Plant away from light-colored pavement. Harvest fruits when ripe or choose a location where staining is not a concern.
