Lanceleaf Coreopsis Seeds - Premium Coreopsis lanceolata for Long-Blooming Gardens

🌿 Coreopsis lanceolata Planting Instructions
Common Name: Lanceleaf Coreopsis
Plant Type: Short-lived perennial (often reseeds itself)
Native Range: Eastern and Central United States
Pollinator Value: Excellent – attracts bees, butterflies, and other beneficial insects

☀️ Site Selection & Sunlight Requirements
Sunlight: Full sun (6+ hours/day) is ideal.
Can tolerate light shade but produces more blooms in full sun.
Soil: Tolerates a range of soils — sandy, loamy, rocky, and even dry soils.
Drainage: Needs well-drained soil; does not tolerate standing water.
pH Range: Neutral to slightly acidic; adaptable to most pH levels.

🌱 Soil Preparation
Loosen top 6–8 inches of soil before sowing.
Remove weeds, grass, and debris.
Add light compost only if the soil is extremely poor — rich soils reduce flowering.
Avoid excessive fertilization which leads to leggy growth and fewer flowers.

🌾 Direct Sowing Outdoors – Fall or Spring
Fall Sowing (Recommended)
When: After the first hard frost, before the ground freezes.
Why: Mimics natural winter stratification, enhancing spring germination.
How:
Broadcast seeds on surface of prepared soil.
Press seeds lightly into soil; do not bury deeply.
Cover with a light dusting (~1/16 to 1/8 inch) of soil or fine mulch.
Water lightly if soil is dry; allow nature to provide moisture and cold exposure over winter.
Spring Sowing
When: After last frost when soil is workable.

Stratification: Optional but recommended — 2–4 weeks of cold moist stratification improves germination rate and uniformity.
How:
Prepare seedbed, scatter seeds on surface, and press lightly into soil.
Lightly cover with no more than 1/8 inch of soil.
Keep soil consistently moist until germination occurs.
Germination time: 10–20 days.

🌱 Starting Seeds Indoors for Spring Transplanting
When to start indoors: 6–8 weeks before last frost date
Stratification: Optional but beneficial. Cold moist stratify for 2–4 weeks in the refrigerator before sowing indoors.
Scarification: Not required

Sowing Indoors:
Sow seeds on top of moist seed-starting mix.
Press lightly into soil; do not deeply bury — light aids germination.
Maintain temperature at 65–75°F (18–24°C).
Cover trays lightly with plastic or humidity dome until germination (10–20 days).
Transplanting Outdoors: Harden off seedlings for 5–7 days before planting out after frost risk is past.
💧 Watering
Keep soil evenly moist during germination and early establishment.
Once established, plants are very drought-tolerant and require minimal watering.
Avoid overwatering or poor drainage, which can cause root issues.

✂️ Maintenance Tips
Deadhead regularly to encourage prolonged blooming and prevent aggressive self-seeding (if desired).
Cut back in late fall or early spring to rejuvenate growth.
May self-sow modestly in garden beds.
Plants can be divided every 2–3 years if desired.
Tends to bloom in early to mid-summer; deadheading can extend blooming through summer.

❌ Is it Invasive?
Not invasive.
Self-seeds readily, but is easy to control and manage in most garden and restoration settings.
A good candidate for wildflower meadows, pollinator gardens, roadsides, and native plantings.

🌼 Other Notes
Pairs well with other native species like Ratibida columnifera, Gaillardia, Echinacea, Liatris, and Monarda.
Excellent for low-maintenance landscapes, xeriscaping, or erosion control on slopes.
Strong ecological value for pollinators and native wildlife.
