Heartnut Tree Seeds

(Juglans sieboldiana cordiformis) Deciduous. Zones 5-8.

The Heartnut tree is named for the shape of the nut - a flattened heart-shaped nut that easily splits into two halves, like two sides of a locket. Native to Japan, it is also known as Japanese Walnut, but it is well suited to our Northern climates. 

The Heartnut kernel is creamy and white, with a smooth, oily texture and deliciously sweet flavour! Like other walnut varieties, heart nuts are high in omega-3s and antioxidants, as well as protein, fibre, and heart healthy fats. Toast the nuts for deeper flavour, chop, and sprinkle on salads, oatmeal, fruit crisps and yogurt. Heart nuts are great in place of pine nuts in pesto! 

Another special quality of the Heartnut tree is its amazing ability to sequester carbon. One Heart Nut tree will pull more carbon dioxide out of the air than 1000 conifer trees! It grows vigorously and will produce nuts after 3-5 years - larger crops when planted together.

** Please note that all members of the Juglans family (Butternuts, walnuts, heartnuts, pecans, etc.) create a protective substance in their roots called Juglone. This can kill certain other plant species within the root zone.

GROWING INSTRUCTIONS

- Soak Seeds 24 hrs. Follow with 120 days cold, moist stratification. For more information on stratification, check out our article "How To Start Your Tree Seeds".

*If you are doing the cold period in your fridge, please check on your seeds. 120 days is an estimate & they may sprout sooner.*

- Plant stratified seeds in pots or a nursery bed using standard potting soil. Heat mats are NOT required & can hinder germination!

- Protect young tree seedlings from slugs, cutworms & rodents. Slugs especially can eat primary leaves as soon as they come up, so be vigilant!
