Important Site Considerations

Plant thoughtfully: Princess Tree can spread aggressively into disturbed natural areas. Assess its suitability for your location before sowing, and avoid planting where seedlings could escape into nearby natural habitats. Allow ample room for its mature size.

How to Start from Seed

1. Fill containers with a well-draining growing mix and moisten evenly.
2. Sprinkle two or three seeds on the surface of each container and press gently into contact with the mix. Do not cover with soil.
3. Place in a bright, room-temperature location. Keep the surface lightly moist with a fine spray rather than allowing it to dry out or become waterlogged.
4. Once seedlings have developed leaves, thin to the strongest plant in each container.
5. Continue growing with adequate light and moisture. Move outdoors after the last spring frost when seedlings are approximately 6 inches tall, gradually introducing them to outdoor conditions before planting.

Growing Expectations

Tree size, growth rate, and flowering depend on climate, site, and care. This listing does not guarantee a specific annual growth rate or time to flowering. Choose a planting site with long-term space and maintenance needs in mind.
