Diplotaxis tenuifolia.

While technically this variety is a perennial, growers and home gardeners will probably prefer growing it as a fast-maturing annual crop. Bellezia Organic arugula features highly upright growth for dense planting and easy harvesting. The leaves are darker green than most, with good looking serrated edges and mild flavour. This is the perfect arugula for raw salads or salad mixes, and it makes excellent microgreens. It is suitable for container growing throughout the year and features intermediate resistance to downy mildew.
