Seedville Royal Paulownia Empress Tree Seeds

This species is known for its rapid growth rate, capable of adding up to 15 feet in height per year under ideal conditions. It is an excellent choice if you are looking for quick shade or a fast-growing landscape feature.

No, these trees are not suitable for container gardening. They are large, fast-growing perennials that require significant space for their root systems and mature height, so they should be planted directly in the ground.

The Royal Paulownia thrives in full sun to partial shade and is quite adaptable to average soil and water conditions. It is generally unfussy, making it a relatively low-maintenance option once established.

These seeds are hardy in USDA zones 5 through 9. If you live within these zones, the tree should be able to survive the winter and return as a perennial each year.

You should plant the seeds outdoors after the danger of frost has passed in the spring. Alternatively, you can start them indoors a few weeks before your area's last frost date to give them a head start.

Because these trees reach a mature height of 40 feet and have a significant spread, you should space them at least 20 feet apart. This ensures they have adequate room to develop their canopy and access necessary nutrients.
