Howard is another walnut variety cultivated in California in the late 20th century. We harvest our Howards during the middle of the season. They produce a large, round smooth nut with a good seal. Tree size is small to medium and semi-upright with moderate vigour, which makes it a good candidate for high-density plantings.
Hartley walnuts came to prominence in 1915 when they won an award as the premium in-shell walnut. Today this “classic walnut” is the principal variety sold in shell. Our Hartley trees are moderate-to-large with moderately spreading and good vigour on fertile soil. They produce approximately 90 per cent light kernels.
