Purvis Hardy English Walnut (Bundle of 2)

Overview

Purvis Hardy English Walnut seedlings are seed-grown Juglans regia selections originating from Bob Purvis’ farm, chosen for its smooth-flavored nuts, good kernel quality, and demonstrated cold tolerance for an English walnut. These seedlings represent a rare cold-climate lineage and are well suited for growers who want to trial English walnuts beyond their typical comfort zone.

Origin & History

These seedlings come from nuts collected in Fall 2023 from a mature English walnut growing on the farm of our dear friend Bob Purvis. They represent a later-generation seedling population derived from Garfield Shults’ original English walnut seed line, which he promoted as cold-hardy “dwarf” Juglans regia—making these trees part of a multi-generational, open-pollinated selection adapted to colder climates.

While the mother tree does not express true dwarfing, it clearly shows reduced vigor compared to most standard English walnuts, topping out at roughly 12–14 feet tall. This makes the line especially interesting for cold-climate growers seeking more compact English walnut genetics.

Fruit & Uses

The mother tree produces smooth, mild-flavored nuts with a pleasant nutty profile and little to no bitterness. Kernel quality is strong, with a good meat-to-shell ratio. These traits make Purvis English Walnut promising for fresh eating, baking, and general culinary use. As with all seed-grown walnuts, some variation should be expected among offspring—but the parent tree sets a high bar for flavor and kernel quality.

Growth Habit

Based on the mother tree, this line exhibits noticeably lower vigor than most English walnuts. Rather than becoming a massive canopy tree, the parent has stabilized around 12–14 feet, suggesting a naturally smaller growth habit (though not genetically dwarf). Final size of seedlings will vary, but growers can reasonably expect moderate vigor compared to typical Juglans regia.

Spacing

Because these are seedling English walnuts with moderate vigor, a practical spacing recommendation is 12-15 feet between trees. If you plan to prune and manage canopy size, you can lean toward tighter spacing; if left largely unmanaged, give them more room to develop.

Pollination

English walnuts are wind-pollinated and generally benefit from having multiple trees for improved nut set due to timing differences between male and female flower maturity (dichogamy). Purvis English Walnut seedlings are not considered self-fertile in isolation; so planting the trees in this bundle together is strongly recommended to ensure reliable pollination and production.

Cold Hardiness

The mother tree has survived into the -20°F range on Bob Purvis’ farm with no reported winter injury. How far below -25°F this genetic line can tolerate is not yet known. For now, we'd place this Purvis Hardy English Walnut conservatively at USDA Zone 4b. As more growers trial these seedlings in colder climates, we’ll learn whether this line can reliably push beyond that threshold.

Other Notes

An especially interesting aspect of this walnut line is its combination of reduced vigor and clean, non-bitter flavor—two traits rarely found together in English walnuts grown this far north. As with all seed-grown walnuts, these are best viewed as a small breeding population: each tree is genetically unique, and part of the value here is discovering exceptional individuals for future cold-climate walnut improvement.
