- Species and varieties: Asparagus officinalis 'Jersey Giant' is a popular variety of asparagus known for its high yield and disease resistance. It is part of the Jersey series of asparagus varieties, which are bred for superior performance.
- Hybrid or heirloom: The Jersey Giant is a hybrid variety. It was developed by Rutgers University and is known for its vigor, productivity, and resistance to rust, fusarium, and crown rot.
