🌱 Sowing Options
1️⃣ Direct Sowing Outdoors
Best Time to Sow:
Fall (ideal in mild climates): For earlier bloom and natural cold stratification.
Early Spring: As soon as soil is workable.
Site Selection:
Sunlight: Requires full sun (at least 6 hours/day).
Soil: Prefers well-drained soils; thrives in sandy or loamy soils. Avoid heavy clay or soggy soils.
Soil pH: Neutral to slightly acidic (6.0–7.0)
Soil Preparation:
Loosen soil to 4–6 inches deep.
Remove weeds and debris.
Optional: Add a small amount of compost if soil is very poor, but avoid heavy amendments.
Planting Depth:
Surface sow or press seeds lightly into the soil.
Seeds need light to germinate, so do not bury them deeply.
If covering, do so very lightly (1/16 inch max).
Watering:
Water gently after sowing.
Keep soil lightly moist until germination (typically 7–21 days depending on temperature).
Once established, low water needs — drought-tolerant.
Stratification:
Not required, but a brief cold exposure (7–14 days) may enhance germination in spring sowings.
Fall sowing naturally takes care of this.
Scarification:
Not necessary.

2️⃣ Starting Seeds Indoors (Spring Transplanting)
When to Start:
4–6 weeks before your last frost date.
Growing Setup:
Use seed trays or small pots with a well-draining seed-starting mix.
Surface sow seeds — do not cover deeply.
Provide bright light (12–16 hours/day) with grow lights or a sunny window.
Watering Indoors:
Mist or bottom water to avoid washing away seeds.
Keep soil lightly moist (not soggy).
Transplanting Outdoors:
Harden off seedlings for 7–10 days before transplanting.
Space plants 6–12 inches apart in full sun location with good drainage.

🔧 Maintenance Tips
Low-maintenance, easy-to-grow annual.
Deadhead to prolong blooming (optional).
No fertilizer needed; does well in nutrient-poor soils.
May reseed lightly in suitable conditions.
Great companion in pollinator mixes, native wildflower beds, and dry gardens
.
🚫 Invasiveness
Not considered invasive.
May reseed mildly in suitable conditions but does not spread aggressively or displace native perennials.
