Asparagus Connovers Colossal

A long-standing favourite for a reason. Connovers Colossal lives up to its name with thick, tasty green spears topped with rich purple tips. It’s known for being reliable, productive, and easy to grow once established—perfect for gardeners who want a steady harvest year after year.

This variety holds an RHS Award of Garden Merit, which means it’s passed rigorous trials for yield, health and reliability. In short—it performs brilliantly without fuss.

SOW: late winter to early spring in modules with warmth (13-16ºC) or in mid to late spring in a nursery bed (2.5cm deep).

GROW: make sure your new permanent asparagus bed is weed free and dig in well-rotted organic matter before planting up. If your soil has poor drainage then perhaps consider using a raised bed. Harden off your seedlings and plant in their permanent position in early summer – plant on the flat. You may get a light cut in the third year if growth is vigorous; look forward to steady cropping from the year after that – stop harvesting in mid-summer to allow plants to recover.

LONG TERM CARE: Asparagus can be productive for 20 years. At the end of the season cut back stems to 10cm above the ground. Mulch with well-rotted manure or compost in the autumn to help suppress weeds. Apply a general fertiliser early in spring. In an exposed garden cover the bed with ferns or straw over the winter. To make good use of the space try growing parsley or basil in between.

ENJOY: Once it’s settled in (give it a couple of years), you’ll be rewarded with generous crops each spring. The flavour is rich and full—ideal for everything from quick steaming to roasting with olive oil and lemon.
