Asparagus beans, also known as yard long beans, are a unique and interesting addition to any garden. While they may resemble pole beans in appearance, they are actually botanically different. Asparagus beans belong to the species Vigna unguiculata sesquipidalis, whereas pole beans belong to the species Phaseolus vulgaris.
One of the main differences between asparagus beans and pole beans is their growth habit. Asparagus beans are vigorous climbers and require some sort of support to grow vertically. They can reach impressive lengths of up to 3 feet or more, hence their nickname “yard long beans.” On the other hand, pole beans also climb, but they typically reach lengths of around 6-8 inches.
Another distinction between these two types of beans is their taste and texture. Asparagus beans have a unique flavor that is often described as nutty and slightly sweet. Their slender and elongated shape gives them a crisp and tender texture when cooked. Pole beans, on the other hand, have a more traditional bean flavor and a slightly firmer texture.
In terms of cultivation, both asparagus beans and pole beans require similar growing conditions. They thrive in warm climates and prefer well-draining soil with plenty of organic matter. Both types of beans benefit from regular watering and should be planted in an area with full sun exposure.
When it comes to harvesting, asparagus beans should be picked when they are young and tender, ideally before they reach their full yard-long length. Harvesting them at this stage ensures that they are still tender and have not become tough and fibrous. Pole beans can also be harvested when they are young and tender or left to mature for dry bean production.
While asparagus beans may resemble pole beans in appearance and growth habit, they are actually a different species altogether. Asparagus beans, or yard long beans, belong to the species Vigna unguiculata sesquipidalis, while pole beans belong to the species Phaseolus vulgaris. Both types of beans have their own unique flavors, textures, and cultivation requirements. So, if you’re looking to add a twist to your bean garden, consider trying out some asparagus beans for a delicious and visually striking addition.
