Sun Requirements ▾

Full sun is ideal in cooler climates, with at least 6 hours of direct sunlight daily. In warmer regions, light afternoon shade may help prolong flowering. Insufficient light can reduce bloom quantity and stem strength.

Watering Instructions ▾

Maintain consistently moist soil throughout the growing season, particularly during flowering. Do not allow soil to dry out completely, as moisture stress can reduce bloom production. Avoid saturated soil conditions, as excessive moisture may lead to root rot.

Care Tips ▾

High Scent Sweet Peas grow best in rich, well-draining soil amended with compost. They prefer cool to mild temperatures and average outdoor humidity. Consistent soil moisture is important during establishment and active growth, and strong vertical support is required for climbing stems. Good air circulation helps reduce fungal disease. Direct sow High Scent Sweet Pea seeds outdoors in early spring once soil can be worked, as they tolerate light frost. Seeds benefit from soaking or light scarification prior to planting to improve germination. Seeds germinate best in soil temperatures between 10–18°C. Plants typically begin flowering in approximately 60–75 days. Regular harvesting of blooms encourages continued flowering throughout the season.
