Kaump, also listed as Harry Kaump, is a winter apple from Wisconsin described in N. E. Hansen's 1902 study of northwestern apples. The source gives no parentage or breeder. It places the cultivar in northern apple trials: the tree was doing well in northern Iowa and was on the trial list of the Minnesota State Horticultural Society [S1].
The fruit is small, roundish, and regular. The skin is yellowish green, sometimes with a dull brown cheek. It has distinct white dots and sometimes russet centers [S1]. Hansen describes an acute, regular cavity with a radiating russet patch; a medium stem; a narrow, small, smooth, abrupt basin; a half-open calyx; an open core; a funnel-shaped tube; median or basal stamens; and few, large, plump seeds [S1].
The flesh is white, fine grained, subacid, and rated good [S1]. The entry calls it a winter apple. A later classification page also places Kaump in a midwinter to spring group, supporting its treatment as a late-keeping cultivar rather than an early dessert apple [S1].
The tree is described as very productive. Its northern Iowa performance and trial status with the Minnesota State Horticultural Society are the main adaptation clues in the available source [S1]. No direct hardiness zone is given. Its cold-climate value therefore rests on those Upper Midwest trial and performance notes, not on a stated zone rating [S1].
Kaump appears in the bulletin as a Malus apple cultivar. The packet gives no taxonomic detail beyond apple context, and no lineage links, sibling cultivars, or later breeding use. The name Harry Kaump may preserve a personal association, but the source does not say whether Harry Kaump was the originator, introducer, or namesake [S1].
