Description

Cucumber Marketmore (Cucumis sativus) is widely regarded as one of the most reliable, heavy-yielding heirloom slicing cucumbers ever bred. Producing smooth, straight, uniform dark green fruits measuring 8 to 9 inches long, it features a crisp, tender texture and a clean, sweet, non-bitter flavor. Highly celebrated for its exceptional disease resistance, it thrives in variable summer weather, keeping vines vigorous and productive long after other cucumber varieties have faded. An essential staple for fresh garden salads, summer slicing, and dipping trays.
