How to Grow Sweet Pea Plants
The sweet pea plant (Lathyrus odoratus) is a climbing annual with delicate, colorful flowers that appear in late spring and last well into summer. Some sweet pea varieties are also very fragrant. This flower does best when planted in a sunny location that receives afternoon shade, especially in regions with very hot summer weather. They prefer rich soil and require frequent watering during dry conditions. Sweet pea seeds germinate well when soil temperatures range from 55 to 65 degrees F. Does this Spark an idea?
