Heartnut is aptly named for its sweetheart shaped nuts and high levels of heart healthy Omega 3 oil (38%). Easy to crack and remove in one piece, harvest is a breeze, which is difficult to do with other members of the walnut family. Bearing at a young age, established or near established trees are very productive with nut clusters of perhaps 20 or more hanging in great abundance. Taste is sweeter, milder and smooth textured compared to  English walnut (Juglans regia), but not as refined as Butternut (Juglans cinerea).  Established trees require very little care. Nut shell interior look like heart locket. Harvest: late September to late October depending on zone, climate, soil fertility, soil moisture, temp.  Averages 60-70 nuts/lb. Resistant to canker disease.

How to germinate Heartnut seeds:

Stored in moist peat at 4C for prompt spring germination. Sow nuts 3 cm deep in a sowing layer consisting of equal parts peat, compost, and 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 and pluck out sprouters as the spring progresses. Check bag often. We get better germination via baggie than direct or pot sowings.
