Sky Blue Petunia 50 Seeds

Sky Blue Petunia is a cheerful annual known for its soft sky-blue blossoms that bring a light, airy feel to gardens, containers, and hanging baskets. The classic trumpet-shaped flowers bloom generously from late spring right through frost, creating a continuous wash of cool blue colour.

Compact yet vigorous, Sky Blue Petunia forms a well-branched plant that works beautifully in borders, patio pots, window boxes, and mixed planters. Easy to grow and fast to flower, it’s a reliable choice for Canadian gardeners looking for season-long colour with minimal fuss.

Planting Instructions 

Indoor Sowing:

• Start seeds 10–14 weeks before last frost

• Surface sow — do not cover seeds, as light is required for germination

• Gently press seeds into moist seed-starting mix

• Keep soil consistently moist (not soggy)

• Maintain warmth (21–24 °C)

• Germination typically occurs in 7–14 days

• Transplant outdoors after all risk of frost has passed and plants are hardened off

Direct Sowing Outdoors:

• Sow after last frost when soil has warmed

• Surface sow and press lightly into soil

• Keep evenly moist until seedlings are established
  (Note: flowering will occur later than with indoor sowing)

Care Tips

• Sun: Full sun for best flowering (tolerates light shade)

• Soil: Well-drained, fertile soil

• Water: Regular watering; containers may need frequent watering in hot weather

• Spacing: 10–12 inches apart

• Height: 8–12 inches (may trail slightly depending on growing conditions)

• Maintenance: Pinch back lightly to encourage bushier growth; remove spent blooms to keep plants tidy

• Hardiness: Tender annual — grown for one season in Canadian climates

Sky Blue Petunia is perfect for gardeners who want easy, nonstop blooms, soft pastel colour, and versatile performance in both garden beds and containers. A classic favourite that never goes out of style.
