Sweet Peas vs Green Peas: Understanding the Difference

When it comes to gardening, both sweet peas and green peas hold a place of importance for enthusiasts and professionals alike. However, despite their similar names, these plants are quite distinct from each other, not just in terms of their uses but also in their cultivation and nutritional profiles. This discussion aims to shed light on these differences, helping gardeners make informed decisions about which peas to plant in their gardens.

What Are Sweet Peas?

Sweet peas, known scientifically as Lathyrus odoratus, are one of the most beloved flowers in the gardening world due to their vibrant colors and intoxicating fragrance. Originating from the Mediterranean region, these annual plants have captivated gardeners and flower enthusiasts for centuries. Sweet peas grow as climbing plants, eagerly twining their tendrils around supports to reach towards the sunlight. They exhibit a wide range of colors, including shades of pink, purple, white, and red, making them a versatile choice for adding splashes of color to garden spaces.

When it comes to growth habits, sweet peas thrive in cool temperatures and are often planted in early spring. They prefer well-drained soil, ample sunlight, and regular watering. Providing a trellis or some form of support is essential for their climbing nature, allowing them to grow healthily and spread their captivating fragrance. Sweet peas are commonly used in cut flower arrangements due to their long stems and appealing scent, making them a popular choice for both home gardens and professional floral designs. In addition to their aesthetic and olfactory appeal, sweet peas can also attract beneficial insects to the garden, playing a role in the ecological balance of garden ecosystems.

What Are Green Peas?

Green peas, scientifically known as Pisum sativum, are small, spherical seeds or the seed-pods of the legume plant. They are considered a cool-season crop, growing best in cooler temperatures and are planted in the early spring. The plants can grow to be over a meter tall, depending on the variety, and they typically require support to thrive. Green peas are known for their bright green color and sweet flavor, making them a popular addition to a variety of dishes worldwide.

These legumes are rich in nutrients, including vitamins A, C, K, and several B vitamins, as well as minerals like iron, phosphorus, and manganese. They are also a good source of dietary fiber and protein. Green peas can be eaten fresh, cooked, or dried and split, which are known as split peas. They are versatile in the kitchen, used in soups, salads, stir-fries, and as a side dish. Their natural sweetness and starchy texture make them a favorite among both adults and children alike.
