Can be planted as a nut-bearing landscape tree. Nuts are thin-shelled, easy to open. Tree's crown is rounded, spreading and open. Prefers deep, dry, light loamy soils. Avoid wet or poor subsoil. Grows 40' to 60', 40'-60' spread. (Partially self-fertile, plant multiple trees to ensure pollination) (zones 5-9)

Hardiness Zones

The carpathian english walnut can be expected to grow in Hardiness Zones 5–9. View Map

Tree Type

This is a nut-producing tree, yielding nuts for human and wildlife consumption.

Mature Size

The Carpathian English walnut grows to a height of 40–60' and a spread of 40–60' at maturity.

Growth Speed Fast Growth Rate

This tree grows at a fast rate, with height increases of more than 24" per year.

Sun Preference

Full sun is the ideal condition for this tree, meaning it should get at least six hours of direct, unfiltered sunlight each day.

Soil Preference

The Carpathian English walnut grows in in acidic, alkaline, loamy, moist, sandy, well-drained and clay soils. It has some drought tolerance.


This tree:
  • Yields a ripened nut crop in mid-autumn. The nuts are slightly oval and 1½–2" in diameter with a smooth, notably thin outer shell (husk) that opens easily when ripe. A light brown, woody inner shell is slightly corrugated and holds the walnut kernel.
  • Begins to bear nuts as early as 4–8 years after planting.
  • Features compound, alternate leaves that consist of 5–9 leaflets with smooth margins that are 2–5" long.
  • Is partially self-fertile, but it is best to plant more than one tree to ensure a good crop (ideally different English walnut cultivars). Wind is required for pollination.
  • Offers nice shade.
  • Is one of the last trees to leaf out in the spring.
  • Grows in a rounded shape.
  • Develops a taproot, making it difficult to transplant.
  • Does not tolerate extreme heat or dryness.

Wildlife Value

The thin shell of the Carpathian walnut makes the kernel more available to wildlife that the harder shelled native black walnut. It is primarily important to squirrels but also appreciated by deer and a variety of rodents


This variety of walnut is native to the Carpathian Mountains eastward to Korea, but was brought to Europe through Persia in early history. Carpathian walnut is a more cold hardy strain of English walnut (Juglans regia) and can be grown further north than English walnut and in climates with more variable winters.
