Scarlet Runner Beans! This nitrogen-fixing legume is not only delicious, beautiful and easily grown in the Bay Area – it’s a perennial. The advantages to planting perennials are numerous. For starters, you don’t have to re-seed each season saving you time and money. Because perennials have several years (in this case usually three) to thrive, their root systems are quite established and can pull important nutrients from deep in the soil.
The Scarlet Runner Bean is hardy to zone 10 and pollinated by bees! Soak the seeds prior to planting and make sure to find a sunny position with ample room for the legume to “run” climb sometimes as high as two meters.
