Manchurian Walnut

Schuettes Oak is a naturally occurring hybrid of Swamp White Oak and Bur Oak. With a faster growth than both parent species, it is one of the fastest growing Oak trees. They are known for growing very large and wide, so space them appropriately. It is considered one of the most adaptable Oaks with little preference on soil conditions. It can handle growing in wet, saturated soils as well as those that are dry, clay, or alkaline.

The Schuettes Oak has very large acorns. They have a large cup portion like the Bur Oak, but without the fringe. Due to the Swamp White Oak parentage, the acorns have less tannins and a sweeter taste. They are a food source for various wildlife including birds, squirrels, and deer.

Manchurian Walnut is a large, broad and often multi-stemmed tree with ornamental qualities. This tree produces large, thick-shelled nuts that ripen in the fall. These edible walnuts are reportedly difficult to crack open. They are useful for attracting wildlife, especially squirrels.

The Manchurian Walnut contains and exudes much lesser quantities of allelopathic compounds, such as juglone (common to walnuts), that may prevent or impair growth of nearby plants. Therefore, it is commonly embraced as a safe walnut to plant.

There are reports of rare this species surviving winters to -45C with specimens growing and thriving in Alaska and Edmonton.

There is no regular supply of this species. It is rare and not produced each year.
