Description Black Sea (also known as Russian 2) is an early-ripening jujube selected for reliable fresh-eating performance. Originating from collections associated with the Black Sea region, it has earned a reputation for finishing fruit dependably in a wide range of climates. Harvested at the crisp stage, Black Sea produces firm, juicy fruit with clean sweetness that works well for fresh eating. When allowed to fully mature and brown, the fruit can also be dried, giving growers flexibility depending on season and preference. In home orchards, Black Sea is often chosen for its consistency. It tends to ripen earlier than many jujubes and maintains usable fruit quality even in seasons where later cultivars can be unpredictable.

Regional Insight: Performs well in many temperate regions, including areas with cooler or variable summers where early-ripening jujubes help ensure a successful harvest. For fresh eating, harvest fruit firm as color begins to develop; allow fruit to fully brown for drying and storage. Explore more jujube varieties in our collection: Jujube Trees
