What are horticultural beans, and how do they differ from other types of beans?
Horticultural beans, often referred to as “dry beans” or “snap beans,” are a specific category of legumes cultivated primarily for their edible seeds and pods. Unlike other types of beans, such as kidney or navy beans, which are grown primarily for their mature seeds, horticultural beans are typically harvested and consumed in their younger, tender form. This makes them a popular choice for home gardens and commercial vegetable production.
Additionally, horticultural beans encompass a wide variety of cultivars, including snap, pole, and bush beans. These beans are known for their rich flavor and versatility in cooking. Their cultivation is often geared toward achieving specific textures and tastes, which can enhance various culinary dishes, setting them apart from other legumes that might be prized more for their nutritional qualities.
