Blue Lake Beans

Phaseolus vulgaris

Overview

Fresh green Blue Lake pole beans

The Definitive Snap Bean for Canning

The Blue Lake bean is arguably the most famous and widely trusted green bean variety in American home gardens, primarily due to its exceptional texture and flavor. The pods are long, straight, stringless, and deliver a classic, savory bean taste. When canned, they retain their color and characteristic crisp "snap," which is why they are the gold standard for preservation.

The Pole variety (the traditional Blue Lake type) is an aggressive climbing vine that produces beans continuously over a long season, unlike the faster-maturing bush varieties. This high yield, combined with its resistance to many common bean diseases, makes it an ideal choice for gardeners aiming for a large harvest.

Texture and Appearance

Blue Lake pods grow 5 to 7 inches long and are smooth, dark green, and uniform in shape. The texture is firm and never mushy when cooked, whether fresh or preserved.

Plant Care and Cultivation

  • Essential Trellising: Install a sturdy trellis, fence, or tepee structure **before** planting. Pole beans must have support immediately to climb and maximize air circulation and yield.
  • Watering: Water regularly, particularly during the flowering stage, but avoid overhead watering to minimize the risk of fungal diseases like rust.
  • Harvesting: Harvest beans frequently—at least every two to three days. This encourages the plant to produce new pods continuously. Overgrown beans become tough and slow down production.
  • Soil: Avoid high-nitrogen fertilizers. Beans prefer well-draining soil and benefit most from compost or aged manure incorporated at planting.

Continuous Harvest

The indeterminate nature of pole beans ensures a supply of fresh beans from mid-summer until the first frost. This prolonged harvest makes them ideal for daily kitchen use and smaller-batch preservation.

The Best for Freezing and Canning

Due to their thick walls and low string content, Blue Lake beans hold their structure better than most other varieties when processed. Blanching and flash-freezing is the best method to retain their crisp texture and vibrant color.
