Description
The seeds of the Beaumontia grandiflora, also known as the Easter Lily Vine or Herald’s Trumpet, are found within thick, woody pods. The seeds themselves are often described as being covered in a lustrous, pure white, silky hair, which is said to be the most brilliant of all “vegetable silks.” Due to the hard outer coat, the seeds require scarification and soaking to aid in germination, which can take a few weeks to a few months even under ideal conditions.

Moderate
Beaumontia grandiflora, commonly known as Herald's Trumpet or Easter Lily Vine, is a vigorous evergreen woody climber native to the mountainous regions of the eastern Indian Subcontinent, southern China, and Southeast Asia. The species produces large, fragrant, trumpet-shaped white flowers and is widely cultivated as an ornamental. Seeds have a hard coat and germinate readily with scarification and warm, bright conditions.

Growing Tips
Sow seeds in early spring on the surface of moist seed compost and lightly press into soil. Scarify seeds before soaking for best results. Cover tray with clear plastic to maintain constant humidity and provide bright, indirect light at 20-25°C (68-77°F). Ensure soil remains consistently moist but not waterlogged. Remove cover once seedlings emerge and gradually acclimate to outdoor conditions. Use artificial lighting if natural light is insufficient. Transplant seedlings to small pots when large enough to handle and grow on in warm conditions before planting outdoors in early summer.
