York Imperial

A lopsided Pennsylvania winter apple, named after Charles Downing called it the "imperial of keepers"

History

Taylor’s account of 1898, quoted by Beach, says the apple arose early in the nineteenth century on a farm next to the then borough of York, Pennsylvania, whose owner, a Mr Johnson, noticed schoolboys visiting the tree in early spring for apples that had wintered on the ground under the leaves1. Finding the fruit in fine condition, he took specimens to Jonathan Jessop, a local nurseryman, who began propagating it before 1830 as Johnson’s Fine Winter1. A state historical marker, dedicated in 1948 at the site of Jessop’s nursery on Springwood Farms, gives 1820 as the year he propagated it2.

Jessop’s trees sold slowly at first, and he dumped the surplus in a hollow beside the turnpike, where farmers coming home from market picked them up and planted them in the lower end of York County1. After the middle of the century Charles Downing examined the fruit, called it the “imperial of keepers” and proposed the name York Imperial; the marker dates the naming to 18551,2. The earliest printed description Taylor knew of was W. D. Brincklé’s, in 1853; the apple became a leading market variety in Pennsylvania, Maryland and Virginia and from about 1880 spread through the Middle West1.

In 1928 American commercial orchards held 3,604,000 trees, 4.5 per cent of the total4. In 1941 it and Stayman Winesap were the leading varieties of the central Atlantic region, and it led in West Virginia and northern Virginia4. In 2024/25 it made up 1 per cent of US production; Pennsylvania was expected to grow 2,699,655 of the 3,707,493 bushels forecast for 2025/26, more than of any other variety in the state5.

SNP data published in 2020 show York Imperial and Newtown Pippin to be parent and offspring, with Newtown Pippin, the older, taken to be the parent3.

The fruit

Well grown, the fruit is above medium to large, roundish-oblate and lopsided, with an oblique axis that made it hard to pare by machine1. The tough, bright, smooth skin is green or yellow, blushed with light or pinkish red and faintly striped with carmine1. The yellowish flesh is firm, crisp, a little coarse and moderately juicy, sprightly subacid at first but becoming mild or almost sweet, and somewhat aromatic1.

It was valued as a keeper: in New York it kept in ordinary storage until April or May unless it scalded, with March its commercial limit1. It scalded badly, however, and once it began to deteriorate went down quickly1,4; Magness gave 120 to 150 days in cold storage4.

Growing

The tree is vigorous and upright-spreading1,4. It prefers heavy clay and seldom does well on light, thin or leachy soils, and in New York the fruit lacked colour, size and quality1. Magness rated it resistant to scab and bitter rot but susceptible to fire blight, cedar rust and spray injury; probably a diploid, it was a good pollinator and partially self-fruitful, blooming in midseason or late4. Colour strains were on sale by 19414.

Uses

The marker’s account calls it an all-purpose apple, excellent for cider and cooking2; Magness rated it fair for dessert and good for cooking4. On average in 2020–2024, 97 per cent of the US crop went to processing5; in Pennsylvania many are grown specifically for juice or applesauce2.

Where the sources disagree

  • The farm. Taylor names a Mr Johnson’s farm next to York1; the marker’s account has Jessop working from grafts of a tree on John Kline’s farm at Hellam2.
  • The first name. Taylor gives Johnson’s Fine Winter1; the marker’s account, citing the York Daily Record, gives Jonathan’s Fine Winter, after Jessop2.
  • Who named it. Taylor credits Charles Downing1; the marker’s account credits Andrew Jackson Downing2.
  • Bearing. Beach found it a fairly regular annual or biennial bearer1; Magness put first bearing at six to eight years and classed it as biennial4.
