Asparagus is dioecious. Dioecious plants produce separate male and female plants. Male asparagus plants live longer and are more productive than female plants.
Excellent all-male asparagus varieties for the home garden include:
- ‘Jersey Giant’
- ‘Jersey Knight’
- ‘Jersey King’
- ‘Jersey Supreme’
- ‘Mary Washington’
- ‘Martha Washington’ are good standard asparagus varieties
- ‘Purple Passion’ is a distinctive variety with purple shears.
(A planting of ‘Mary Washington’ or ‘Martha Washington’ will include both male and female plants.)
