Description

The red bean (Phaseolus coccineus) is prized for its bright red flowers that attract bumblebees and honeybees, making it both ornamental and productive. Its large, marbled seeds are a salad classic in Austria. It tolerates slightly cooler sites better than the common garden bean and can be grown as a perennial if the tuber is wintered frost‑free.

Care instructions

Set up a tall, sturdy trellis and plant the large seeds around mid‑May (week 20) about 4 cm deep at the base of the stakes. The red bean requires more water than other beans, water thoroughly during dry periods, otherwise the flowers will drop. Harvest the pods young as a vegetable bean or allow them to fully dry for marbled dry beans.

Companion planting

Good neighbors

cabbage family (Brassicaceae)

particularly well established

Leguminous plants collect nitrogen in the soil, from which Brassicaceae benefit as heavy feeders.

carrot family (Apiaceae)

Peas and beans provide carrot and celery with nitrogen and grow as shallow-rooted plants without competition next to each other.

gourd family (Cucurbitaceae)

Beans and peas enrich the soil with nitrogen, which cucurbits, as heavy feeders, can make good use of.

Rather not

amaryllis family (Amaryllidaceae)

particularly well established

Allium species inhibit the nitrogen‑fixing rhizobia of legumes through their root exudates, which slows their growth.
