‘Mary Washington’ asparagus (Asparagus officinalis ‘Mary Washington’) is a very hardy perennial vegetable grown for its tender, flavourful green spears harvested in spring. A recognized heritage variety, it is prized for its productivity and longevity.
Harvesting usually begins mid-May to June in Quebec, once the plants are well established (usually from the 2nd or 3rd year). After the harvest period, the feathery foliage develops and contributes to the plant's vigour for subsequent seasons.
It prefers deep, rich and very well-drained soil, in full sun. A permanent planting can produce for 15 to 20 years.
The discreet flowers are visited by pollinators.
