Green beans are shorter and come from various common bean plants. They have almost the same nutritional profile as yard long beans but differ slightly in flavor. Their pods come in a single color and have various favorable optimum temperature conditions.

There are several ways in which yard long beans and green beans are different. They include:

Yard long beans are a climbing type of cowpea. As such, they need support from other plants to grow and develop well. Green beans come from the common bean plant and can be either pole beans or bush beans. They, therefore, don’t require any support to grow.

However, both the bean varieties have nitrogen fixing abilities and can thus, be used to boost soil quality.

Type Of Genera

There are many different types of legumes, common beans, cowpeas, soybeans, etc. Yard long beans belong to the cowpeas genera – Vigna unguiculata. This is the same genera that black-eyed beans belong to.

Green beans are obtained from common bean plants which belong to Phaseolus lunatus. The beans are harvested from various common bean plants when they’re still immature, making them have green pods.

Therefore, yard long beans are more closely related to black-eyed beans than green beans. That’s so because the former two belong to the same genera that differ from the latter.

Appearance Of Pods

Both yard long beans and green beans have edible pods. However, the pods don’t look the same.

Besides length, yard long beans usually have pale green smooth pods that may be spiral, linear, or curved. The pods may sometimes have a purple or brown color.

However, yard long beans have different heat tolerance from green beans. Yard long beans can withstand more heat and prolonged cooking. For this reason, they are perfect for recipes involving longer cooking times like stews. Green beans have low heat tolerance and are perfect for dishes that don’t require prolonged cooking, like stir-fries and salads.
