American Bladdernut
Carpathian English Walnut

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.

Carpathian English Walnut is a great shade tree or a fantastic addition to a food garden. The taste is described as having a full flavour with a hint of sweetness and butterscotch. They are great for fresh eating, cooking, and baking. Thin shelled nuts split right down the center, making them easy to crack. Harvest ranges from late September to early October.

It is known for being highly productive and more cold hardy than other English Walnut varieties.
Carpathian English Walnut is considered to be self pollinating but planting with a second variety will result in greater yields. It can be cross pollinated with Black Walnut and others.
