Scarlet Runner Bean - Key Growing Information

An attractive planting of scarlet runner bean vines; some can reach as high as 9 feet or more.

DAYS TO GERMINATION:

Seedlings appear in 4–7 days at 60–70°F (16–21°C).

SOWING:

For transplants, sow 2–3 weeks before the last frost, 2 seeds 1" deep in each cell packs
or containers. Thin to one plant per cell or pot, harden off, and plant out after the last frost.
Direct seed: After the last frost, once the soil is at least 60°F (16°C), sow 1" deep at about 6 seeds per foot, thinning to 4–8" when true leaves appear.
A nitrogen-fixing inoculant can boost flowering and bean yields. Plants need a trellis or other support.
LIGHT PREFERENCE: Full sun.

SOIL REQUIREMENTS:

Fertile soil rich in humus.

PLANT SPACING:

Space plants 4–8" apart.

HARDINESS ZONES:

Grown as an annual.

HARVEST:

Edible flowers: pick when they show strong color, either in bud or fully open. Unopened buds keep 2–3 days in the refrigerator on a slightly damp towel in a covered container; use open flowers right away. Keep picking the beans so the plants keep flowering.

USES:

Edible flowers, and a quick cover for arbors, walls and fences.

SCIENTIFIC NAME:

Phaseolus coccineus
