It is no wonder that Conover’s Colossal was developed specifically for market farmers: this variety is hearty, vigorous, and sure to please with its buttery, tender spears. This 19th century heirloom is still beloved by market farmers and home gardeners today. Produce merchant S.B. Conover of New York City developed it in the 1860s, selecting for the superior market qualities of massive spears and super high yields. This superb variety has been praised by the likes of famous 19th century market gardener Peter Henderson, as well as the Royal Horticultural Society. Spears can reach one inch thick and remain supremely soft and juicy. This heirloom asparagus is a true culinary delight and not to be missed.

Easy to grow, disease resistant and delicious, Mary Washington has been the absolute gold standard for green asparagus varieties for the last century. During the early 1900s a fungal disease called Asparagus Rust travelled from Europe to the Americas, ravaging the U.S. asparagus crop. Plant explorer and breeder J.B. Norton, who worked at the USDA and with a group of Massachusetts asparagus growers, collected seeds from all over the East Coast and in Europe. He trialled countless varieties, using advanced statistical data to find successful varieties, and ended up with a group of resistant asparagus types that he called Washington. ‘Mary Washington’ showed to be incredibly vigorous, and resistant to the rust. His achievement was hailed as a huge success for asparagus breeding. This scrumptious and reliable heirloom has rightly reigned supreme in gardens and on farms since it was introduced in 1919. Norton went on to dedicate the remainder of his career to breeding work with the Pedigreed Seed Company, which specialized in, you guessed it, asparagus.
