Please use the oversized shipping (+2cm) option as these are large nuts and do not fit Canada Post’s standard mail. We will omit from the order and refund.
Manchurian walnuts are known by several names, but for some reason “tigernut” just brings a smile to my face. Relatively rare in commerce, this East Asian species is known for its hardiness and ability to produce nuts in Alaska’s short season growing season. Asian walnuts (including heartnut) bear in as many as 20 nuts per cluster. I recommend wearing protective head gear when the nuts are falling. Nut meat can be difficult to extract but a lovely nutmilk can be made using the same method for Shagbark hickory by the American First Nations where the nuts are crushed, simmered, and strained to give a nutritious rich beverage.
Fast growing and can start producing nuts in 5 years. If you have the urge to breed productive short season hardy hybrid walnuts, this species could provide a good foundation.

How to germinate Juglans mandshurica seed:
Soak in very warm (not hot) water. Repeat 2x over 24 hrs. Small bubbles should effernese as nuts hydrate. Sow nuts 3 cm deep in a sowing layer consisting of equal parts peat, compost, & coarse sand. Use deep pots as this species puts down a very large tap root. Apply a thin top layer of fine mulch. Needs 90-120 days of cold stratification to germinate at 20 C in the spring/early summer. Alternate germination technique: baggie sow the nuts in a large clear plastic bag and mix nuts with just moist medium of equal parts coarse sand and peat. Check bag; pluck out sprouters as they emerge. Check bag often. We get better germination via baggie than direct or pot sowings. Use and secure protective ½” hardware cloth to protect nuts from rodents. The dang things will make a real mess of emerged seedlings if there’s any nutmeat left in the shell. Guaranteed!
