Dwarf Grey Sugar Edible Pod Pea Seeds Heirloom Vegetable. An edible pod pea first introduced sometime before the early 1890’s (dates we have researched vary quite widely – some sources indicate dates almost 40 years sooner). This is the earliest maturing and most dwarf sugar pea. The 6 cm (2.5″) long fibre-free pods are light green, curved, sweet and very tender.
