Unusual pink-orange flowers are produced from May to September. Climbs to 2.4m tall in full sun and a moist but well-drained soil.
Keep picking the flowers, or remove the dead flower heads before they become seed pods, to keep new flowers coming.
These sweet peas require a structure to climb up, e.g. a trellis, fence, hemp netting, or similar. We grow ours up an old tree.
