Its genetics lean more toward the is English heritage with paper thin easily cracking shells and well filled nuts. There is enough J. nigra genes to impart superior walnut blight resistance, drought tolerance, vigorous growth, cold tolerance and the nut meat have a slightly more robust taste. Self fertile.

How to germinate Julglans regia hybrid 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.
