Upland Cress – Barbarea verna

Barbarea verna is a biennial member of Brassicaceae. Its yellow, four-petalled flowers develop into slender dry pods. Unlike aquatic watercress, Nasturtium officinale, this species is terrestrial and needs less water. That distinction makes the botanical name useful when a seed assortment includes several plants sold as cress. The catalogue average is 800 seeds per gram, a useful reference when comparing bulk quantities.
