How to Sow (Recommended for Zone 3)

• Direct‑sow as early as soil can be worked, since Texas Bluebonnet requires cool temperatures to establish.
• Scarify seeds lightly to encourage germination (rub gently with sandpaper).
• Sow ¼ in deep and keep lightly moist until sprouted.
• Choose a sunny location with sandy or well‑drained soil.

Indoor Start Option (Optional)

• Start 4–6 weeks before transplanting using cool soil (10–15 °C).
• Transplant carefully—lupines dislike root disturbance.
