Vines often are 4 to 5 feet long, but when grown alone, field pea's weak stems prevent it from growing more than 1.5 to 2 feet tall.
Leaves have two leaflets and a tendril.
Flowers are white, pink, or purple. The root system is relatively shallow and small, but well nodulated. Growth is slow during winter but increases rapidly in warm spring weather. Environmental preferences and limitations Field pea requires cool, moist growing conditions and can withstand heavy frost once established. It does not grow well in hot weather and is not suitable as a summer cover crop.
