Cobaea seeds — cup-and-saucer cathedral bells
Cobaea, the cup-and-saucer vine or cathedral bells, is one of the fastest and most spectacular climbers from seed — large bell-shaped flowers that open creamy green and deepen to violet-purple, set in a leafy green “saucer,” scrambling metres up a support in a single season. It sits within our climbing flower seed range. New to flowers? Our flower growing guide gets you started.
Few climbers cover a fence so fast — the calendar shows when to sow.
A fast screen with late nectar
Self-clinging by tendrils, cobaea is a superb choice among climbing flowers for clothing a trellis or arch, and its big late-season bells are valuable to bees, placing it among our pollinator-friendly flowers.
Growing cobaea from seed
Sow under cover in early spring, setting the large flat seed on edge, and keep it warm. Plant out after the last frost into full sun with a tall, sturdy support and rich, moist soil. Once warm it grows with astonishing speed, flowering from midsummer until the frosts.
