It is native to temperate coastal areas of Asia, Europe, and North and South America, including Argentina. The plant grows trailing stems that are typically 50-80 cm long and found on sand and gravel storm beaches. The leaves are waxy glaucous green, pinnate, 5-10 cm long, and have 2-5 pairs of leaflets, with the terminal leaflet usually replaced by a twining tendril. The inflorescence has a long stem and produces racemes of up to twelve broad flowers that are dark purple in color with paler purple wing and keel petals. The fruit is a long brown pod up to 50 mm in length. Beach Pea flowers in mid-to-late summer. Beach Pea is a rare houseplant that requires regular watering and thrives in long-lasting, direct light, less than 1 foot from a window. It prefers well-draining soil and can benefit from gentle, organic fertilizer during the peak growing season. The plant belongs to the Lathyrus genus and is native to Western and Northern Europe. To get rid of Beach Pea, put on gloves and gently pull out the plant with the root system, or use a shovel for convenience.
