Cultivation

Origin: in Lafayette, Ind., by Purdue Univ. Introd. in the 1940s. Parentage unknown; original scionwood from a Jonathan tree of unknown origin planted in Purdue Univ. orchards probably in the 1920s; used in conjunction in studies with Virginia crab apple stocks. Tree: Fruit: skin very dark red; flesh firm, dry; long storage life; apparently when grown on seedling rootstocks without the use or influence of Virginia crab, then it is not as well-colored as Jonared or Blackjon and does not have as good storage qualities. Not to be confused with Blackjon. No longer being propagated.
