Rivikasvi

Rivikasvi, also known as *Lathyrus vernus* or spring vetchling, is a perennial flowering plant native to Europe and parts of Asia. It belongs to the Fabaceae family, commonly known as legumes or peas, and is often cultivated for its ornamental value and edible seeds. The plant is characterized by its delicate, pale pink to purple flowers, which bloom in early spring, typically from March to May, depending on the climate. Its slender stems can reach heights of 20 to 50 centimeters, with trifoliate leaves that add to its attractive appearance.

Rivikasvi thrives in well-drained soil and prefers partial shade to full sun, making it adaptable to various garden conditions. It is often used in wildflower meadows, borders, or as a ground cover due to its rapid growth and ability to suppress weeds. The plant is also valued for its ecological benefits, as it fixes nitrogen in the soil, improving fertility for neighboring plants.

While rivikasvi is primarily grown for decorative purposes, its seeds are edible and have been used historically in some cultures as a food source. However, caution is advised, as some species in the *Lathyrus* genus contain neurotoxic amino acids, such as beta-oxalylaminoalanine (BOAA), which can cause neurological disorders if consumed in large quantities. Rivikasvi itself is generally considered safe in moderation, but proper identification and moderation are recommended.

This plant is low-maintenance and drought-tolerant once established, requiring minimal care beyond occasional watering and deadheading to encourage prolonged flowering. It is also resistant to deer and rabbits, making it a practical choice for gardens in areas with wildlife pressure. Rivikasvi is often propagated through seeds, which are sown in autumn or early spring, ensuring a reliable presence in gardens year after year.
