The 'Connover's Colossol' variety of asparagus will produce a large harvest of sweet tasting spears that are perfect for salads. The spears produce are much thicker than any green variety and taste sweeter. To plant simply dig a hole 20 cm deep, place the root-ball in the hole and cover with soil. You can buy one to five asparagus plants with this order, getting better value the more you order.
