"In the 1820s, Quaker orchardist/clockmaker Jonathan Jessop received a seedling from a Hallam-area (north east od Cleveland, below Lake Erie) tree that had produced apples that kept all winter on the ground under a blanket of snow.
Jessop grafted a stem from this seedling onto another tree on his Springwood Farm in York Township.
He carried the tree to the Friends' Yearly Meeting in Baltimore and from there members brought the tree to Virginia."So Jessop became largely known for his role in development of Imperial apples.
The apple original was known as Jonathan's Fine Winter and later was changed to "Imperial of Keepers" and "York Imperial."
Johnathan Jessop was also a watch maker, and engineer, and born in Gilfford County NC.
I first ran into this variety when my daughter's music teacher asked me to graft her a York Imperial apple. In the process of fining scion wood I ate my first York, an instant favorite.You can buy York trees from Millers Nursery: http://millernurseries.comhttp://
