Austrian winter peas are a cool season pea; they will last through winter, unlike ICP's. I have never had deer eat them well, despite planting them on many properties for years. The ones with white flowers are more palatable to deer than the purple flowered varieties, but there is no way to tell which kind you have until they bloom (unless you buy Nutrigreen peas). You will never find them to draw deer like iron-clay's do; if it were me, I'd just skip 'em, but try them if you want, they fix N like any legume, so it won't hurt to plant them, in the worst case the deer just ignore them.
