Lathyrus japonicus, commonly known as the beach pea, is a climbing perennial plant in the Fabaceae family. It is native to coastal areas of the Northern Hemisphere, including North America, Europe, and Asia. The plant is known for its beautiful purple flowers and its ability to stabilize sand dunes. It has a dormancy period during the winter months.
Lathyrus japonicus thrives in temperate climates and prefers full sun exposure. It requires moderate temperatures and humidity levels. Regular watering is necessary, but the soil should be allowed to dry out partially between waterings. The plant can tolerate a range of temperatures but prefers moderate conditions.
土壌
The beach pea prefers well-draining loamy soil. It can tolerate sandy soils but performs best in a loamy mix. Good drainage is essential to prevent root rot. The soil should be kept moderately moist but not waterlogged.
