Runner Bean "Scarlet Emperor" Seeds | Mr Fothergill's

Our phaseolus coccineus Runner Bean "Scarlet Emperor" seeds are a reliable favourite and possibly the most popular runner bean of all time. The red-flowered plants produce heavy crops of smooth, dark green pods reaching 30-37cm (12-15in) in length that can be served as a vegetable in a traditional roast, or cooked into a variety of dishes. These beans are highly nutritious, and a good source of vitamin C, folate, iron, and fibre. The Scarlet Emperor is early to crop, excellent for freezing, and also makes a great exhibition bean.

Runner beans are easy to grow. Below we address some common queries:

  • Hardiness: this species is half-hardy and must be protected from frost.
  • Planting In Pots: suitable for growing in pots 20-30cm (8-12in) deep or larger.
  • Position: place in full sun for best results.
  • Soil Types: sow in well-cultivated, fertile soil.

Germination Requirements: temperature needs to be at least 10°C for seeds to germinate.

Planting Distance (Seed Tray): sow seeds 5cm (2in) deep in small pots, or 5cm (2in) apart.

Planting Distance (Ground): sow seeds 5cm (2in) deep 30cm (12in) apart in rows set 45cm (18in) apart.

Soil Preparation: remove weeds and large stones, dig in some organic matter during spring, but avoid adding manure immediately before planting.

Thinning: this species do not require thinning.

Seeds Jargon

  • F1 Hybrids: hybrid seeds are produced from two specially selected varieties that are kept in isolation. As they are produced from only two plants, seeds are almost identical genetically.
  • Open Pollinated: open pollinated plants aren't isolated from other varieties, so are more genetically diverse.
  • Heirloom: heirloom seeds are historic, some going back to Victorian times, others more recent. Heirloom varieties can be good or bad, depending on how careful the breeder is to maintain genetic similarity.
Hybrids vs Open Pollinated

As hybrids are produced from two specially selected varieties, the quality is more consistent, with a higher germination rate and improved cropping. But, as they require time, resources and know-how to create, they come to the market at a higher cost. They are also genetically unstable, and so if you keep the seeds from the resultant crop, performance is usually poor. Open Pollinated seeds are highly diverse and have often been grown for successfully for decades. Seeds from the resultant crop are usually perform well.

Annual, Biennial and Perennial

Annual plants complete their life cycle within a year, biennials in two years (usually only flowering in the second year) and perennials can live on indefinitely.

Hardy, Half-Hardy and Tender

Hardy and half-hardy plants can survive a light frost, but the latter are best moved indoors during periods of bad weather. Tender plants must be kept indoors, until after the last frost.

We believe that anyone, regardless of ability can successfully grow their own plants at home, and do so in an eco-friendly and sustainable way.
