PHASEOLUS vulgaris 'Tricolor'
Plant Common Name
Pole Bean, Tricolor Pole Bean
What a colorful and tasty mix of pole snap beans; green, purple and yellow beans dangle from the long vines of the green 'Blue Lake', purple 'Purple Peacock' and yellow wax pole beans in this mix. The long, crispy beans are produced on productive, vigorous plants, yielding fresh beans about 60 days after sowing seeds. A good harvest size is 5 to 6 inches (12 to 15 centimeters) long.
Bean leaves are trifoliate (three-leaved), arranged in an alternate fashion on the stem and have somewhat diamond-shaped leaflets. Leaflets are green, though the leaves of 'Purple Peacock', have hints of purple. The flowers are typical of peas or beans: larger, rounded petals subtend smaller petals that form a lip or keeled beak. The blooms are produced in loose clusters on short stalks among the foliage and may be white to pinkish lavender. Modern bean cultivars are self-fertile. If harvested young, the immature bean pods are eaten. If allowed to mature, the dry, hard seeds can be hulled, 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.
Pole beans are upright vines that can reach great lengths, so they require staking or other support.
