Green Asparagus (Asparagus officinalis ‘Millennium’) is a highly productive Canadian variety prized for its straight, firm, uniform, bright green spears. Their tender texture and mild, slightly sweet flavour make them an excellent choice for fresh table use. After harvest, the fine, feathery foliage reaches 120 to 150 cm in height and remains attractive throughout summer. Hardy to Zone 3, this perennial vegetable performs exceptionally well in northern climates and is perfectly suited to Quebec gardens. Once established, a planting can produce generous harvests for more than twenty years.
Plant the asparagus crowns in spring at a depth of 15 to 20 cm, spacing them 30 to 45 cm apart in loose, organic-rich, perfectly drained soil with a neutral to slightly alkaline pH. Choose a location in full sun and water thoroughly after planting, then regularly during establishment. Mulch helps conserve soil moisture and suppress weeds. Apply compost every spring to maintain vigorous growth. Avoid harvesting during the first two years so the root system can develop fully and support long-term production.
Ideal for permanent vegetable gardens, edible landscapes, and perennial kitchen gardens, ‘Millennium’ asparagus grows well alongside tomatoes, parsley, basil, and marigolds. Harvesting generally begins in the third year, from May to June, and returns reliably each spring. The spears are delicious grilled, roasted, sautéed, or steamed and are also excellent in salads, risottos, pasta dishes, and omelettes. After harvest, allow the foliage to develop fully so it can replenish the roots, then cut it back only after it has completely yellowed in autumn.
