ActivePrunus domestica L. · European plum
Walter Hartmann c/o Universität Hohenheim
10 August 2026
The fruits are large or very large, reaching a mass of 80–120 g, and have a round, slightly flattened shape. The skin is colored dark burgundy, almost black. The flesh is amber-hued, firm, fleshy, and aromatic, possessing a sweet taste with low acidity.
The tree is distinguished by vigorous growth and a rapid rate of development, forming a compact, vertical-type crown. The variety is self-fertile; however, the use of pollinator varieties is recommended to increase yield. The tree requires about 400–500 hours of chilling period for flowering.
