Corydalis sempervirens (Rock Harlequin) Organic, Non GMO - Flower

Corydalis sempervirens (Rock Harlequin) Organic, Non GMO - Flower 

Corydalis sempervirens, commonly known as Rock Harlequin, is a delicate and beautiful biennial wildflower. Native to North America, this plant features finely divided, fern-like foliage with soft green hues. It produces tubular, pink to purplish flowers with contrasting yellow tips. Blooming throughout the summer, these flowers are attractive to pollinators, particularly bees. Corydalis sempervirens is often found in rocky or disturbed areas, such as cliffs, forest clearings, and recently burned land.

Growing Requirements:

• Light Requirement: Full sun to partial shade.

• Soil: Prefers well-draining, sandy, or rocky soils, though it can tolerate various soil types as long as there is good drainage. It thrives in poor, nutrient-deficient soil.

• Watering: Requires moderate watering, but it is drought-tolerant once established. Avoid overwatering, as it may not thrive in waterlogged soil.

• Temperature: Hardy in cooler climates but tends to perform well in temperate regions. The plant does well in USDA zones 3-7.

• Annual or Biennial: Corydalis sempervirens is a biennial, meaning it completes its life cycle in two years. In the first year, it forms a rosette of leaves. In the second year, it sends up flowering stems, blooms, and then sets seed before dying.

• Bloom Time: Summer, from June to August.

Seed Stratification Process:

. Cold Stratification:

Corydalis sempervirens seeds require a period of cold stratification to break dormancy and encourage germination.

• Place the seeds in a damp paper towel or peat moss.

• Seal them in a plastic bag.

• Store the seeds in the refrigerator for 60-90 days.

2. Planting After Stratification:

• After the cold stratification period, sow the seeds directly into prepared soil in your garden or in seed trays. Ensure the soil is well-draining.

• Cover seeds lightly with soil, about 1/8 inch deep.

• Water gently but thoroughly.

Germination and Care:

• Germination Time: Seeds should germinate within 2-4 weeks once sown after stratification.

• Spacing: Space plants about 8-12 inches apart to allow proper air circulation and growth.

• Fertilization: Corydalis sempervirens does not typically require fertilization, as it thrives in poorer soils.

• Weeding and Maintenance: Keep the area weed-free to reduce competition for nutrients and moisture. Little maintenance is required once the plant is established.

Self-seeding:

Corydalis sempervirens readily self-seeds, which means it can return year after year even though it is a biennial. Allow some of the flowers to go to seed if you wish to encourage this process. However, it is not considered invasive.

With the right care and conditions, Corydalis sempervirens will bring lovely color and pollinators to your garden!
