Blue Moon Wisteria is a striking, flowering vine, and the hardiest of the wisterias. Up to three times in one growing season you can expect showy, fragrant, lavender-blue flowers.

Make sure you plan your site as this vine requires a structure to support its mature weight. Try planting close to a post, trellis, or fence.

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.
