Other Information


Lathyrus grandiflorus, also known as large-flowered everlasting pea or perennial pea, is a perennial herb in the family Fabaceae. It is native to Europe and Asia and typically grows in fields, meadows, and other disturbed areas. The plant has pinnate leaves and large, pink or purple flowers that bloom in the summer. The root of the plant is not edible, and it is not considered to be toxic. The seeds of Lathyrus grandiflorus are also toxic and not to be consumed, eating large amounts of them over a period of time can cause a neurological disorder called lathyrism.


The Two-flowered Everlasting Pea, Lathyrus grandiflorus, is a beautiful and unique flowering plant that belongs to the family Fabaceae. This plant is native to North America and is often found in meadows, prairies, and open woodlands.

One of the most distinctive features of the Two-flowered Everlasting Pea is its attractive flowers. The plant produces clusters of two to six large, showy flowers that are typically pink, purple, or white in color. The flowers are about an inch in size and have a sweet fragrance that attracts bees and other pollinators.

The Two-flowered Everlasting Pea is a perennial plant that grows up to three feet tall and two feet wide. It has a deep taproot that allows it to survive long periods of drought. The plant is also able to fix nitrogen in the soil, which makes it an important component of natural plant communities.

This plant is relatively easy to grow and care for. It prefers full sun or partial shade and well-drained soil. It can be propagated by seed or by dividing the roots in the spring. Once established, the Two-flowered Everlasting Pea requires little maintenance, although it should be watered regularly during dry spells.

In addition to its ornamental value, the Two-flowered Everlasting Pea has some practical uses as well. The plant has a long history of use in traditional medicine to treat a variety of ailments, including respiratory infections, digestive problems, and skin conditions. The seeds of the plant are also edible and were once used as a food source by Native American tribes.

The Two-flowered Everlasting Pea is a beautiful and valuable plant that adds color and diversity to natural plant communities. Its showy flowers, easy-to-care-for nature, and practical uses make it a great choice for gardeners, naturalists, and anyone who appreciates the beauty and diversity of the natural world.

The Two-flowered Everlasting Pea is also known as Large-flowered Sweet Pea, and it is closely related to the more familiar garden sweet pea (Lathyrus odoratus). However, the Two-flowered Everlasting Pea is a wild plant and not commonly grown in gardens, although it can make an excellent addition to a naturalistic or wildflower garden.

The plant's ability to fix nitrogen in the soil makes it an important species in many ecosystems. Nitrogen is an essential nutrient for plants, and it can be limiting in some soil types. By fixing nitrogen, the Two-flowered Everlasting Pea provides a valuable resource for other plants growing in the same area.

In addition to its nitrogen-fixing ability, the Two-flowered Everlasting Pea is also a host plant for several species of butterfly, including the Clouded Sulphur (Colias philodice) and the Orange Sulphur (Colias eurytheme). These butterflies lay their eggs on the plant, and the larvae feed on the leaves, helping to control the plant's growth and providing a food source for other wildlife.

Like many plants, the Two-flowered Everlasting Pea is threatened by habitat loss and fragmentation, as well as by invasive species and other factors. As a result, conservation efforts are underway to protect the plant and its natural habitat. These efforts include habitat restoration, seed collection and storage, and research on the plant's biology and ecology.

The Two-flowered Everlasting Pea is not only a beautiful and useful plant, but it also has a fascinating cultural and historical significance. The plant has been used by various Indigenous communities for thousands of years for food, medicine, and cultural purposes.

For example, the Blackfoot people of North America used the plant to make a tea that was believed to help with chest pains and respiratory problems. They also used the plant as a dye for textiles and to make decorative items such as earrings and necklaces.

The Two-flowered Everlasting Pea was also used by the Cherokee people to treat wounds, while the Navajo people used it as a remedy for coughs and colds. The plant was also used as a food source by various Indigenous communities. The young leaves and shoots were eaten as a cooked vegetable, and the seeds were roasted and eaten as a snack.

Today, the Two-flowered Everlasting Pea continues to be used by some people for medicinal purposes. The plant is believed to have anti-inflammatory, diuretic, and laxative properties, among others. However, it is important to note that any use of plants for medicinal purposes should be done under the guidance of a qualified healthcare professional.

In conclusion, the Two-flowered Everlasting Pea is not only a beautiful and ecologically important plant, but it also has a rich cultural and historical significance.
