Botanical Name

PHASEOLUS vulgaris 'Trionfo Violetto'

Plant Common Name

Pole Bean, Purple Pole Bean, Trionfo Violetto Pole Bean

General Description

An Italian heirloom pole bean, ‘Trionfo Violetto’ is both beautiful and delicious. It produces large quantities of flat, deep purple pods, which are complemented by striking, purple-veined foliage. The beans have an outstanding, sweet flavor, and are best when picked very young and tender. They begin ripening approximately 75 days from sowing.

Plant beans in full sun and fertile, evenly moist, well-drained garden loam after the soil has warmed and all danger of frost has passed. Seeds should be sown directly in the soil at a depth of about three times their width. Pole types such as this should be spaced about a finger’s length apart beneath a trellis, in rows wide enough to allow easy access. If planted beneath a pole or bamboo teepee, seeds should be sown in groups of six beneath each support. Overwatering seeds prior to germination may cause them to rot, so be sure to keep them moderately moist, never wet. Tossing the seeds in a commercially available inoculant (Rhizobium inoculums) may be beneficial, but is not essential for success. Unlike bush beans, pole varieties continue to bear throughout the growing season. Harvest every few days to ensure maximum production.

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