Jersey knight is a predominantly male variety of Asparagus. Male varieties are preferred by many gardeners, males are far more productive in producing abundant spears. Female plants energy is squandered producing seeds and rogue plants.

Rutgers University in New Jersey conducted a program to improve the performance of asparagus that concentrated on the productivity of male plants. The strains that resulted, most of which bare the name Jersey are considered the most productive of Asparagus plants. They yield about 25 percent higher than older heirloom, mixed sex and female varieties.
