smaller than other walnut trees and beautiful shape
Vivian C on Oct 2, 2016
I have a 5 year old daughter and we eat store bought nuts together such as cashews, almonds, pecans, etc. and I thought this would be a great addition to our diet. Not only is it healthy and tasty but it grows in the shape of a heart and I think she will love that aspect also since I'm really getting them for her.

I chose heartnuts because of reading about them, and think they will be flavored like a cross between hickory nuts and pecans and shell out pretty easy .

Are its roots toxic to other fruit trees?
Henry R on Apr 1, 2018
BEST ANSWER: The roots product/emit a very small amount of juglone, but not anywhere near the amounts found in a black walnut. By paying attention to the spacing requirements between trees, you should be avoid any chance of your fruit trees being affected.

Love it
I bought this tree 4 years ago. I was planning on removing all of the black walnut trees because I detest the taste. The second year we harvested 18 nuts; third year at least 100 nuts; this year too many little nuts starting out to count. We didn't cut down the black walnuts because we decided they were at least giving shade...good thing because....the butternut we bought to pollinate the heart nut has never had buds or nuts. Those black walnuts are apparently doing the job. Love this tree; grew fast; produced fast and gives good shade. Really tasty nuts too. Cool 3 D heartshape; looks good in variety Christmas nut baskets, etc.

So much better tasting than any other walnut.
My trees aren't mature enough to produce yet, but I've tasted heartnuts. Unlike other walnuts, there is absolutely no bitterness or bitter aftertaste. Just a pure walnut taste. They open like a locket with just a hammer tap on the edge... and the meat often comes out in one piece. You need to plant two trees for proper pollination. But if I remember correctly, heartnut trees are smaller than many nut trees.

I've loved Stark's for years. In general, their trees (of all types) are always better quality than ones I've ordered from other sources. It can be quite a dramatic difference in size and health.

In the rare cases I have had a problem, they do stand by their replacement policies. You get what you pay for with Stark's so don't hesitate to order from them.

no output above the graft
on the tree I received, the first year it had output of leaves all over the tree. But the second year, it only put out buds below the graft.

Heart nut results
Both trees didn't survive the first winter. They were too small to start with. Don't think they were well established enough. I will not be trying them again.

Heartnut Trees
I am so excited about my purchase of the Heartnut Trees. Sadly one of the trees died. But I am thrilled the other one us alive. And I am anxious to get another one. It will be so exciting to some day see the trees produce heart shape nuts to enjoy.

Growing well
The 3 heartnut trees I purchased from Stark grew about 4 feet the first year and survived the winter 5a (Palo,IA) fine. Too early to tell how many will bear heartnuts vs revert back to Japanese walnuts.
