The Garden Bean Gets Its Due in 2021

green beansThere are many species of beans in cultivation around the world, yet it’s the common garden bean, Phaseolus vulgaris, that takes on celebrity status as National Garden Bureau’s vegetable focus for 2021.

One of the earliest cultivated plants, garden beans can trace their beginnings to Central and South America. Vining or climbing beans were an original member of the “Three-Sisters” — a companion planting of the first domesticated crops of maize, winter squash and climbing beans. These became the three main agricultural crops used for trade and food for Native North Americans.

Green beans were once referred to as string beans due to the long, fibrous thread along the pod seams. Calvin Keeney developed the first stringless green bean in 1894 and later became known as the “father of the stringless bean.”

Breeders continue to breed this stringless trait into modern genetics. Other desirable traits include dark-green succulent pods, good bean flavor, concentrated fruit set, stress tolerance and disease resistance.

Basic Types of Garden Beans

The common garden bean is anything but common. Green beans, or “snap” beans as they are also referred to, come in a variety of flavors, pod shapes, sizes and a colorful pallete including shades of green, purple, yellow and speckled bicolors.

  • Bush beans are the workhorse of the garden and the mainstay in the kitchen. They’re compact and fit well into both small garden patches or patio containers fitted with cages.
  • Pole beans, with their vining habits, can be trained up poles, trellises, netting or supportive structures such as a teepee. With proper support, you can also grow pole beans in containers.
  • Filet beans, or Haricots Vert (French green beans), are distinguished by elegant, ultra-slim pods. Due to their delicate appearance, Filet beans are gaining in popularity with foodies and chefs. Filet beans come in both bush and pole bean types.
  • Dried or shelling beans are grown for their edible seeds rather than edible pods. Pinto beans, kidney beans and black beans fall into this category.

Garden Beans Growing Tips

  • Beans are warm-weather vegetables and are best planted after soil temperatures reach 70 degrees.
  • Avoid sowing too early in the season. Cool, wet soils can lead to rot.
  • Beans thrive with at least eight hours of daily sun, moderate fertility and well-drained soil.
  • They have shallow roots, so weed carefully to prevent damage to the root system.
  • Mulch the soil around the bean plant; consistent moisture results in the highest quality harvests.
  • Beans are quick to mature, and harvests can begin 50-60 days after sowing.
  • Bush beans typically grow 12 to 24 inches tall and produce harvests for about three weeks.
  • Succession sowing of bush beans every two to three weeks will produce delicious beans all season.
  • Pole beans have a long harvest season, generally lasting about six to eight weeks.
  • Harvest frequently to encourage pod production.
  • Pole beans can quickly grow a lush privacy wall around porches or patios.
  • Create a living fort or teepee with pole beans for a fun play space.
  • Yellow wax beans lack chlorophyll and will retain their beautiful golden color when cooked.
  • Purple beans contain anthocyanins (the purple pigment) that disappear when beans are cooked.

Harvesting Tips

A good indication of when to harvest is to reference the days to maturity for the specific variety. Pick green beans when pods are young and tender, just before the seeds begin to swell. Beans will “snap” when you bend and break them. If they are immature, they won’t snap.

Fresh, unwashed green beans should remain fresh for up to a week when stored in a reusable container or plastic bag in the refrigerator.

Versatile in culinary preparation, garden beans can be eaten raw, steamed, boiled, stir-fried, grilled or baked. For the best eating experience, cooked green beans should still have a crisp texture and an appetizing, bright-green color.

Green beans pair well with a variety of herbs, spices and flavors. Parsley, rosemary, sage, savory, thyme, a splash of lemon juice or a pat of butter are very popular additions to bean dishes.

You can’t go wrong with the simple addition of garlic and onions. And some people swear green beans cry out for bacon bits or a dollop of bacon grease added to the cooking pot.

Green beans are bred for eating fresh or processing and preserving. Some varieties are well suited for both. Processing green beans are better able to retain their beautiful color and texture for canning, pickling and freezing. If you look forward to gifting out jars of pickled green beans, a processing green bean will yield you the best results.
