Northwest Poplar

American Bladdernut is a fast-growing, ornamental shrub native to eastern North America. It can be grown as a large shrub or trained as a small tree. The small, drooping, white flowers are bell-shaped and grow in clusters. They appear in mid to late spring, attracting various pollinators. Well suited as an understory plant as it prefers shady and partial sun location with moist soils.

The blossoms mature into papery seed capsules and have been described as miniature Japanese lanterns. They are commonly used in dried flower arrangements. The seeds found within the pods are edible, and have a taste similar to pistachios. They can be eaten raw, used in baking or made into a sweet cooking oil.

Care should be taken when planting American Bladdernut, as it can spread quickly. It is prone to suckering and will self-seed. Plant the right tree in the right place.

Northwest Poplar is a large and fast-growing tree. Due to its wide spread, this tree makes a great shade or shelterbelt tree. Northwest Poplar tolerates partial shade, drought, and most types of soil. This poplar produces no fuzz.

Northwest Poplar continues to be popular as a shelterbelt species due to the great cost savings that come from the wide spread of the branches. It is a staff favorite because of the wonderful shade it provides all summer long.
