Stratified Heavenly Blue Morning Glory Seeds

Stratified Heavenly Blue Morning Glory Seeds

Stratified • Untreated • Organic • Non‑GMO

Heavenly Blue Morning Glory (Ipomoea tricolor ‘Heavenly Blue’) is the classic sky‑blue climber that has graced fences and arbors for generations. Our seed lots are pre‑stratified, giving you a head start on germination and strong, uniform early growth.

This vigorous annual vine produces large, luminous blue flowers with pale throats, opening fresh each morning through the warm season. Stratification mimics cool‑season dormancy, helping break the hard seed coat and improving sprouting once soils warm.

Growth Habit: Fast‑growing annual vine
Bloom Color: Clear sky‑blue with pale center
Height: 8–12 feet with support
Sun Requirement: Full Sun
Sowing Depth: 1/4 inch

Planting Instructions:

• Stratified seeds may still benefit from a brief soak (6–12 hours) before sowing.
• Sow outdoors after danger of frost has passed and soil has warmed.
• Provide a sturdy trellis, fence, or arch for climbing.
• Keep soil evenly moist during germination (typically 7–21 days).
• Morning glories prefer lean soil—avoid heavy nitrogen fertilization.
• Train young vines early for best coverage and display.
