Black Coat Runner Bean (Heirloom 70 Days)

One of the oldest runner beans seeds still available to grow in your garden today. Vines grow to 6-7’ producing attractive glowing crimson flowers. Mature pods encase large lustrous black seeds. Young pods can be used fresh like green beans, large filled out pods as a shelling bean, or allow to dry on the plant and use as a dry bean. 

25 seeds



Phaseolus coccineus

Germination: 7-14 days

Germination Temperature: Optimum soil temperatures 60-75ºF

Seed Sowing Depth: 1” deep 

Starting Indoors: 2-3 weeks before the last frost. Sow 1-2 seeds per cell/pot.  Provide 70-80ºF soil temperature. Sowing into individual biodegradable peat/cow pots reduces root damage when transplanting. Transplant after last frost, 8-12" apart.

Sowing Outdoors: After the last frost with soil temperatures above 55-60ºF. Sow 4-6” apart, thin to 8-12". Planting in soil under 60ºF results in poor germination. 

How much does a packet plant: 8-10 foot single row 

Harvest: Young tender snap beans until they become fibrous; steamed, baked, boiled, or sautéed. Young seeds can be shelled and cooked like lima beans. Dried beans take a long time to cook and can be soaked 6-8 hours before cooking. Add the edible flowers to salads

Tips: Provide support with a trellis, fence, or poles. Keep beans harvested to encourage more flowers. Grow in light, well-drained soil, provide adequate, even moisture, especially at flowering time. Dry soil can result in low yields and fibrous pods. Do not over-fertilize with nitrogen which results in a surplus of foliage and low, delayed pod growth. Adding inoculant at planting time aids in a larger harvest and more robust plants.

various vegetables mid summer

Black runner beans selected for flower color not bean. Pleased with flower result. Not many beans. Lettuce second planting coming along well. Super snap peas done with good yield. Potato grown in bag and all producing small to medium size. Lemon grass last of 3rd planting small but ready to plant outside Mexican mint. Plants coming to bloom sooner than previously experience. Sunflower love them. Good variety of types and appreciate the short stature easier to pick. The first blooms had very short stem, but that seems to be changing with subsequent blooms. Black Kim tomato first time variety for me. Seems to be more meaty than Cherokee. However the shape of the bottom is often dimpled in the bigger size. Given some to neighbors and have enough to supply the local Food Bank next week. Zucchini is doing just fine. One plant producing 2-3 fruits per week. Melon lilliput has first melon maturing looking great. Mouth already watering. Yard long beans were not as expected. The bean is barely a foot long and pink. After 3 weeks stopped producing. Other green variety (another vendor) is still producing as expected. Eggplant good year culturally so this plant is doing very well few seeds and great flavor if picked small. THANK YOU FOR MAKING MY GARDEN A SUCCESS

They’re growing, they’re blooming, and we’re looking forward to beans!

The beans germinated, took off up the supports and are blooming their little heads off. Now, we’re starting to see beans form. We look forward to interesting meals. Thanks for such great vegetable seeds! Frank & Rosemary Horstman
