Produces a heavy yield of large, flavorful nuts that fill their shells well. Similar to the standard Barcelona variety, but with fewer blanks and with a low incidence of shriveled kernels and moldy nuts. A long bloomer over a long receptive period. Oregon State University release with resistance to Eastern Filbert Blight disease and high resistance to big bud mite. Commercial orchardists are planting York or Yamhill to pollinate at the beginning of its receptive period, and Eta or Theta to cover the late blooming period, to ensure maximum potential yield. Seedlings were open pollinated with Yamhill and Eta, all blight resistant selections. As seedlings, Jefferson Hazelnut will be slower to come into bearing than cloned varieties and will be variable in nut size, yield and overall quality, though, with their superior genetics will tend to be vastly superior to average seedling hazelnuts. Seedlings are not meant for commercial production except as a rootstock for grafting. The seedlings are great for hedgerows, erosion control, wildlife plantings and backyard orchardists wanting economical trees.
ZONE: 5-8
POLLINATION/BLOOM TIME: If not a seedling, needs pollinator(s) for long bloom period. Seedlings can self-pollinate. Commercial orchardists are planting York, Felix or Yamhill to pollinate the 85% of the beginning of its receptive period, and Eta or Theta to cover the remaining 15% of its late blooming period. Jefferson's pollination period tends toward late-mid.
RECOMMENDED GROWING AND CARE:
Full sun, balanced moisture, mildly acidic soils and good drainage. Can be trained as standard with single stem, or allowed to grow as bush and sucker freely.
CHILL HOURS: Medium-high: 800 - 1000 hours below 45F
DISEASE RESISTANCE: Good. Blight resistant and probable high resistance to big bud mite.
SIZE AT MATURITY: To 12' tall x 12' wide.
RESTRICTIONS: CAN NOT SHIP TO OR
