is a popular hybrid variety known for its vibrant color, excellent flavor, and high market value. It performs best in moderate temperatures, as extreme heat can lead to bolting and affect head quality.

Characteristics:

1. Head Formation: Riva produces medium to large, round, and firm heads that are densely packed.
2. Color: The outer leaves and heads are a deep, rich purple-red color, which enhances visual appeal and makes it a favorite for fresh markets and salads.
3. Taste: Known for its sweet and slightly tangy flavor, Riva is excellent for raw consumption in salads, coleslaw, and garnishes, as well as for cooking.
4. Growth Habit: This variety has a strong, upright growth habit that promotes good air circulation and reduces the risk of fungal diseases.
5. Disease Resistance: Riva is resistant to common cabbage diseases such as black rot and downy mildew, which helps ensure healthier crops and reduces the need for chemical interventions.
