How to Grow Purple Beans


Purple beans grow into glorious, rich purple plants that create a dramatic display in the garden or in a basket when harvested. Once cooked, these tender morsels turn green and provide a tasty addition to any meal. For a touch of color that is sure to please the child in any gardener, grow purple bush beans and bring a little excitement to the garden.

Things You'll Need

  • Purple bean seed
  • Garden tools
  • Compost/Fertilizer
  • Choose a location that receives at least six hours of direct sun each day. Prepare the soil by tilling to a depth of 8 to 10 inches. Remove any rocks, roots, or other debris and rake smooth with a garden rake.

  • Mark rows with the edge of a garden hoe. Add compost to the row and work in well with existing soil. If you prefer to use commercial fertilizer, apply it according to the manufacturer's directions and work it in well with the existing soil. Do not use more than recommended or you will risk burning the seeds or young roots.

  • Plant bean seeds to a depth of 1 inch and space 2 to 4 inches part. Cover firmly with loose soil and pack down lightly with your hands or the base of the hoe. Space rows 18 to 24 inches apart.

  • Water throughly and keep evenly moist until the seedlings emerge in seven to 10 days, depending on weather conditions. Use care in watering bean seeds. Too much water and cool conditions can cause the bean seed to rot in the soil before germinating. Water whenever the soil dries completely. Beans are drought tolerant and do not require much watering, but will gladly accept it when offered.

  • Weed by hand or hoe gently to maintain a weed-free growing environment. Use care when hoeing near bean plants because the shallow roots are easily disturbed.

  • Harvest when beans are 4 to 6 inches long before the pod has filled out. Eat as a tasty snack of fresh veggies or boil in salted water until tender and a rich green. Serve as a side dish drizzled with a little melted butter. Add a little cream for an old country favorite.

Tips & Warnings

  • Avoid picking beans when they are wet. This will cause them to "rust" and turn an unsightly brown.
