Beach Pea, also called Circumpolar Pea, Sea Vetchling Pea and Sea Pea, is mostly found along our immediate coast on sea dunes and amongs driftwood. Don't get it confused with Everlasting Peavine, which is native to Europe and is on the Washington Noxious Weed Control Board's Monitor list. It has a broad native range that extends throughout North and South America, Europe and into Asia becuase Beach Pea seeds can remain viable while floating in sea water for up to 5 years! This plant flowers in mid to late summer showing dark and light purple which attract butterflies. Beach Pea is a host plant for Eastern Tailed Blue Butterfly larvae.
