Bedford Darkmar 21 Brussels Sprout Seeds

[200–210 days] Bedford Darkmar 21 is a time-tested heritage variety known for its excellent cold tolerance and well-formed, medium-sized sprouts. Grown in UK gardens for generations, it’s particularly valued for its late cropping—providing delicious harvests from December through February when fresh greens are in short supply.

The sprouts are tightly packed, dark green, and flavourful—ideal for steaming, stir-fries, or roasting. Bedford Darkmar 21 is a hardy, upright plant that stands well in exposed sites and continues producing even in harsh winter conditions. This makes it a top pick for gardeners looking to reliably extend their harvest into the colder months.

An excellent choice for both kitchen gardens and allotments, especially where a reliable overwintering crop is needed.
