Moderate
Bauhinia acuminata, commonly known as Dwarf White Bauhinia or White Orchid Tree, is a tropical flowering shrub native to Southeast Asia, valued for its fragrant white flowers and ornamental appeal. Seeds exhibit physical dormancy and require scarification combined with warm water soaking to achieve good germination rates (85% at 25-27°C). This species is widely cultivated as an ornamental in tropical and subtropical regions.

Soaking — 24 hours
Soak seeds in hand-hot water (50°C) for 12-24 hours, or in room temperature water for 24 hours before planting

Mechanical scarification
Gently scarify or sand the seed coat to improve water absorption and enhance germination rates

📋
Additional notes
Combine scarification with warm water soaking for best results. Swollen seeds should be sown immediately after soaking. Unswollen seeds require scarification.
Substrate & Container
Recommended substrate
well-draining peat-based seed mix or peat-perlite mixture
Recommended container
seed trays or individual pots
Growing Tips
For optimal germination: (1) Combine mechanical scarification with 12-24 hour warm water soak at 50°C or room temperature; (2) Use a free-draining peat-perlite mix to prevent damping-off; (3) Maintain consistent moisture but avoid waterlogging; (4) Keep seedlings in warm conditions (25-27°C) and provide high humidity using a humidity dome or plastic cover; (5) Expect germination within 2-4 weeks under ideal conditions; (6) Transplant seedlings with 4-6 true leaves into larger containers; (7) Avoid pressing seeds into substrate as they should be lightly covered; (8) Spring sowing yields best results due to consistent warm temperatures.
