Botanical Name

PHASEOLUS vulgaris 'Super Marconi'

Plant Common Name

Pole Bean, Roma Bean

General Description

Broad, black-seeded Roma-type pods are borne on the vines of pole bean ‘Super Marconi’. This vigorous bean produces long, flattened, green pods that are surprisingly tender and stringless for their size. Beans are ready for harvest 73 to 77 days after sowing. Like many modern cultivars, ‘Super Marconi’ is self-fertile.

After the danger of frost has passed, plant 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. Pole beans require trellising to produce a good crop. Plants should be spaced from 6 to 12 inches (15 to 30 cm) apart. Overwatering 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 and to pick the pods at their most tender.

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.
