Empress Tree
Hardy Pecan

The Empress Tree is a fast growing, ornamental shade tree. It has purple, fragrant flowers that are quite attractive. The flowers emerge before the leaves in early spring. The leaves of this tree can grow very large, up to 30 cm long.

As one of the fastest growing trees in the world, this tree has been given considerable attention for carbon sequestration projects. It drops many seeds which can make it invasive in warmer climates. Please do some research and plant the right tree in the right place.

The Empress tree’s genus name comes from Princess Paulowna, daughter of Tsar Paul I of Russia.

Hardy Pecan trees are known for their edible nuts that ripen in late autumn. They can be eaten raw or cooked and can be used in a wide range of baked goods. If stored properly in a cool, dry location, they can be kept for up to 6 months in their shell. Trees tend to bear nuts at maturity, which occurs around 6 -10 years. The size and form of this tree also makes it a great shade or feature tree for your landscape.

For nut production, it is recommended that at least 2-3 are planted so that cross pollination can occur. In colder areas it is likely that nut production will be limited, especially in locations with late frosts and shorter growing seasons.

If exposed to high winds, Hardy Pecan is known to lose branches, but these can be used as firewood, or to smoke foods with a hickory flavour. Finding seed or seedlings of this tree is rare in Canada.

Note: plant this tree once. It will not respond well to transplanting.
