Growing Instructions

Planting Season

Late summer and fall are suitable for sowing freshly collected seeds. Outdoor sowing allows seeds to experience natural seasonal temperature changes.

Seed Preparation

Pacific Bleeding Heart seeds benefit from warm, moist followed by cold, moist stratification. Soaking seeds before sowing may also help with preparation.

Sowing Method

Fill seed trays or small pots with a well-draining, moisture-retentive seed-starting mix. Sow seeds individually and cover them lightly with growing medium.

Sowing Depth and Spacing

Sow seeds approximately one-eighth inch deep. Keep enough space between seedlings for healthy root and foliage development. Established plants can be spaced approximately twelve to eighteen inches apart.

Sunlight Requirements

Place seed trays in a sheltered location with suitable light and temperature conditions. Once established, grow plants in partial to full shade. Gentle morning sunlight is generally suitable.

Soil Requirements

Choose rich, humus-filled soil that retains moisture while providing good drainage. Adding leaf compost or well-rotted organic matter helps improve soil structure.

Watering

Water gently after sowing and maintain consistent moisture throughout germination. Avoid allowing the growing medium to dry out completely. Established plants also appreciate regular watering during dry periods.

Germination

Pacific Bleeding Heart seeds have natural dormancy and benefit from a warm-cold-warm treatment.

A practical approach is to provide a period of warm, moist conditions followed by approximately sixty to ninety days of cold, moist stratification. Return the seeds to suitable growing temperatures afterward. Germination can be irregular and may take several months or longer.

Transplanting

When seedlings develop healthy true leaves and become strong enough to handle, carefully transplant them into individual pots. Move established young plants into their permanent shaded garden locations while minimizing root disturbance.

Fertilizing

Prepare the planting area with mature compost before transplanting. Established plants generally need only occasional compost applications. Avoid excessive fertilizer.

Plant Care

Keep the surrounding soil moist, remove competing weeds, and apply leaf mulch to help retain moisture. Remove damaged foliage when necessary and monitor for slugs and snails.

Flowering and Maturity

Pacific Bleeding Heart generally produces its attractive pink, heart-shaped flowers during spring and early summer. Established plants develop fern-like foliage and may spread gradually through underground rhizomes.

Important Growing Note: Pacific Bleeding Heart is an ornamental plant. Its plant parts should not be eaten, as ingestion can cause adverse effects. Keep seeds and plants away from children and pets
