Bush beans are a classification defined by the plant’s growth pattern, describing varieties of the common bean, Phaseolus vulgaris. These varieties grow in a compact and self-supporting manner. They are a common garden crop, valued for their ease of cultivation and efficient space use in a vegetable patch.
Defining the Bush Bean Growth Habit
Bush beans are characterized by determinate growth, meaning the plant grows to a specific, finite size before stopping its vegetative growth. These varieties typically reach a height of only 1 to 2 feet, forming a dense, shrub-like structure. Their sturdy, upright stems eliminate the need for external support like trellises or stakes. When the main stem terminates in a flower cluster, the plant shifts its energy to the reproductive phase.
This growth pattern results in a concentrated period of flowering and subsequent pod production. The harvest is often ready all at once, usually within a two-week window, which is ideal for processing large batches for canning or freezing.
Differentiating Bush Beans from Pole Beans
The difference between bush beans and pole beans lies in their growth patterns. While bush beans are determinate, pole beans are indeterminate, continuing to grow foliage and flowers until stopped by frost or disease. This indeterminate habit allows pole beans to develop long, vining stems that can reach up to 10 to 15 feet, necessitating a vertical support structure. Bush beans require more horizontal garden space but are suitable for small plots or container gardening since they use virtually no vertical space.
The yield patterns also differ significantly. Bush beans offer a single, heavy yield of pods over a short duration, maturing quickly (40 to 60 days). Pole beans provide a smaller, continuous harvest over a much longer period, typically beginning production in 55 to 65 days. Maintenance for bush beans is lower because no support system is involved.
Popular Bush Bean Varieties and Their Uses
The bush growth habit is found across the three main culinary types of Phaseolus vulgaris: snap beans, shelling beans, and dry beans.
Snap Beans
Snap beans are eaten pod and all, including popular varieties like ‘Blue Lake 274’ and ‘Contender’ favored for fresh eating, canning, or freezing. These can come in various colors, such as yellow-podded wax beans or the deep purple ‘Royal Burgundy’.
Shelling and Dry Beans
Shelling beans are harvested when the seeds inside the pod are fully formed but still soft, such as cranberry beans. Dry beans are left on the plant until the pods completely dry out. Many staple varieties like navy beans, black beans, and kidney beans are grown on compact bush plants and are prized for their hearty texture and rich flavor in soups, stews, and baked dishes.
