Plumeria rubra, commonly known as red frangipani or red plumeria, is a tropical deciduous tree native to Mexico and Central America, prized for its intensely fragrant flowers. Seed germination is variable and requires consistent warmth and moisture, with successful germination typically occurring within 7-14 days under optimal conditions but sometimes extending to 30 days when conditions are suboptimal.
Before sowing
Soaking in warm water is the primary pre-treatment method. Viable seeds can be identified by sinking in water after soaking.

What to expect
Tips
Maintain soil temperature between 75-95°F (24-35°C) for fastest germination at 85°F. Use a heat mat to sustain warm temperatures. Keep soil moist but never waterlogged to prevent damping off and root rot. Ensure excellent air circulation and use sterile seed mix. Seeds do not need light to germinate but seedlings require bright, indirect light once they emerge. Remove plastic covers once seedlings appear to prevent fungal disease. Fresh seeds have significantly better germination rates than old seeds. Do not soak seeds for longer than overnight as this can damage them.
