First of all, the differences between plants

Sweet pea is an annual twining herb, about 0.9 to 1.8 meters high, and the plants are hairless.

Pea is an annual climbing herb, about 0.5 to 2 meters high, green, smooth and hairless.

Second, the difference between leaves.

Sweet bean leaflets are oblong or ovoid, about 3 to 5 cm long and 1 to 2 cm wide, all around.

Pea leaves have 4 to 6 leaflets, which are oval, about 2 to 5 cm long and 1 to 2.5 cm wide.

Third, the difference between flowers.

Sweet pea flowers are solitary or 1 ~ 3 flowers are axillary, and the corolla is white or purplish red.

Pea flowers are solitary in leaf axils, or several flowers are arranged in racemes, and the colors are usually white and purple.

Fourth, the difference between fruits.

The pods of sweet beans are oval, about 5 to 10 cm long. The pods are lined with paper, and the seeds are round, generally 2 to 10, which is turquoise.

Pea pods's fruit is swollen, oblong, about 2.5-10cm long and 0.7-14cm wide, sharp, with round and turquoise seeds.

Fifth, the diet is different.

Sweet beans are generally tender than peas. They can be used not only for cooking, but also for stewing soup. The outer pods of sweet beans are edible, fresh and delicious, and rich in nutrition. But old sweet beans generally have hard outer pods and cannot be eaten.

The pods outside peas are also inedible, and generally only the beans inside are eaten.
