Dennis, also called Dr. Dennis, is an Americana plum grown from seed of Hawkeye by H. A. Terry at Crescent, Iowa. It first fruited in 1891. The South Dakota bulletin treats it as a named seedling, not a major advance, and preserves it mainly as part of the record of regional plum selection and trialing. [S1]
The fruit is described briefly. The account says it is medium in size and does not color well. A. Norby reported only a fair crop. [S1]
South Dakota experience was not favorable. The bulletin says Dennis had fruited there for several years but was of no special value. It adds that it was not equal to many other plums ripening in the same season. [S1]
In the broader plum record, Dennis matters less as a celebrated introduction than as evidence of seedling selection work built around hardy American plum material in the upper Midwest. Its documented parent is Hawkeye. The packet gives no later breeding or descendant context beyond that origin note. [S1]
