Heartnut is a seed sport (genetic mutation) of Japanese walnut (Juglans ailantifolia) that produces a beautiful, Valentine-heart-shaped nut. Compared to Persian walnuts, heartnuts tend to be hardier and more disease-resistant. They are very vigorous (growing up to 5' a year!), rapidly producing a wide, spreading canopy that creates dappled shade. An great ornamental shade tree for the backyard. Best in zones 5a-7. Heartnuts are nutritious and delicious, and apparently they're at their best after 4-8 years (we haven't managed to save any this long). They can be stored at room temperature and are the sweetest of all walnuts. While they can be difficult to crack with a regular nutcracker, they crack easily with stronger crackers or a hammer, often with the heart-shaped nut coming out perfectly intact.

Genetics: These seedlings are from trees here on Denman Island. After the previous owners left the property, the trees continued to grow and produce for several years without irrigation. All heartnut seedlings have a wide degree of genetic variation, and some may revert back to normal Japanese walnuts with a thicker shell. For this reason, heartnut seedlings are on the more experimental end of the walnut-growing spectrum. Recommended spacing of mature trees is approximately 40', but planting more densely (~10' apart) will help ensure adequate pollination when trees are younger, and enables eventual selection of the most vigorous, productive trees with the best nuts. Trees will grow rapidly and nuts can be expected 4-8 years after planting, maybe earlier. They may be partially self-fertile, but we recommend at least two trees to ensure the best crop. 

Planting: heartnuts want deep, moist, fertile, well-drained soil with pH 5 to 8. They do well on north- and east-facing slopes, and they like to be protected from high wind and frost. They will do best in full sun (at least six hours) but can tolerate partial shade (expect slower growth and reduction in yield). Avoid excessively gravelly or sandy soils (chestnuts or pine nuts would be better suited). Walnuts need ample moisture but they won’t tolerate long periods of standing water. 

Why seedlings? Growing seedlings from productive, vigorous parents helps maintain diversity (each seed is a new variety) while drawing on some of the best genetics for chestnuts in our bioregion. In other words, by planting seedlings, you are participating in the breeding and selection of new, regionally-adapted varieties! We’ve selected excellent parent stock, but we recommend planting several of these trees closer together and selecting your final tree once they've produced their first nuts (4-8 years). 

Why potted? If you won't be planting your trees right away and you don't feel sure about storing bare root trees then you want potted trees.  Potted trees will allow you more flexibility with transplanting timelines and late spring installations, however, they are more expensive to produce and to ship.

Our nuts are grown in tree pots, which are designed with a large opening at the bottom to air prune the root. When the taproot reaches the bottom, instead of circling around, the opening enables the root to gently 'self-prune' itself, stimulating the growth of feeder roots further up.
