Windham is recognized as having improved winter hardiness over Austrian-type winter peas. Windham has a dwarf growth habit and an upright canopy. Windham is a white flowering tannin-free pea, making it sweeter than Austrian-type peas. Wildlife and foraging animals prefer these sweeter peas over purple flowering varieties. Windham was developed in the Northwest as a joint venture between the USDA_ARS and three universities in Idaho, Washington, and Montana.

Winter Hardiness

In 2010-11, Windham was evaluated in Central Ohio alongside Austrian winter peas. According to Richard Leslie, who observed the plots on May 12th, 2011, “Windham Winter Peas interseeded in rows with Daikon Radish, survived the winter (as they did in another trial I observed) while Austrian Winter Peas did not. Windham Winter Peas had spring rhizobium nodules on the roots of the spring plants I dug.”
