Empress Tree
Smooth Sumac

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.

Smooth Sumac is an excellent shrub for both its ornamental appeal and tolerance of difficult planting sites. You'll love the attractive pyramidal spikes of hairy, red berries that emerge on female plants and the fern-like foliage that covers both male and female varieties.

Ensure you give Smooth Sumac enough space to spread out due to its high suckering nature. While not ideal for small, urban yards, this shrub will make a stunning border along a woodland edge or roadside.

Note:These plants typically reach maturity and make their sex easily known (females producing fruit) in their 3rd or 4th year of growth. Our seedlings are too young to identify their sex.
