PHASEOLUS vulgaris 'Blue Lake 274'

Plant Common Name

Blue Lake 274 Green Bean, Bush Bean, Green Bean

General Description

A compact variant of the tried-and-true ‘Blue Lake’ pole bean, 'Blue Lake 274' produces loads of flavorful green beans on bushy plants. These plump beans are ideal for canning and ready for harvest around 55 days after sowing. Be sure to pick them when young and tender to avoid strings and toughness. Like many modern bean cultivars, this selection is self-fertile.

Bean leaves are trifoliate (three-leaved), arranged in an alternate fashion on the stem and have somewhat diamond-shaped leaflets. The flowers are typical of peas or beans; larger, rounded petals subtend smaller petals that form a lip or keeled beak. They are produced in loose clusters on short stalks among the foliage and may be white or pinkish. Modern bean cultivars are self-fertile. If harvested young the immature bean pods are eaten, as with green or wax beans. If allowed to mature, the dry, hard seeds can be shucked, stored and eaten at a later date, as with black beans or pintos.

After the danger of frost has passed, plant bush beans in full sun and fertile, evenly moist, well-drained garden loam. Seeds should be sown directly in the soil at a depth of about three times their width. Bush types should be spaced about a finger’s length apart, in rows wide enough to allow easy access to the plants. Over watering seeds prior to germination may cause them to rot, so be sure to keep them moderately moist, never wet. To ensure a longer harvest, successive plantings may be made two to three weeks apart, continuing through midsummer. Tossing the seeds in a commercially available Rhizobium inoculant may be beneficial, but is not essential for success. Harvest beans every few days to keep plants producing.

Originating from regions of Central and South America, common beans have been cultivated for many centuries. These frost-tender vegetables are grown as summer crops in cooler temperate climates; whereas in warm, tropical zones they are planted as fall and winter crops.
