Magnify glass

Asparagus Connover's Colossal


Exceptionally high yielding

An outstanding source of fibre and vitamins, well worth the wait as each spring the first delicious spears emerge.


Grows well in an open sunny spot with some protection from harsh winds.


Best in light, fertile, well-drained soil. Avoid waterlogging over winter. Add homemade garden compost or well rotted manure to the soil before planting. Plant in raised beds or raised rows in your veg patch and keep the soil weed free. Best not to harvest in the first two years (to allow it to become established) then harvest the early spears but allow the later ones to develop the fern-like leaves, these will return nutrients to the roots as they die down in autumn.

A traditional variety introduced in the 1800's
