Lobelia Pendula Regatta Sky Blue

Lobelia Pendula Regatta Sky Blue Seeds

(Trailing Lobelia — Soft Sky Blue with White Eye, RHS AGM, Regatta Series)

Regatta Sky Blue has a trailing habit perfect for mixed combinations and hanging baskets, with a height of 15–20 cm and spread of 25–30 cm. It performs best in partial shade and is recommended to be planted along with other cool season crops for best blooming.

Sky Blue occupies a uniquely soft and versatile position within the full Regatta color range and the broader trailing lobelia palette. Regatta Sky Blue produces an abundance of sky-blue blossoms that cascade gracefully over the edges of hanging baskets, larger containers, and colorful bowls — blooming up to 4 weeks earlier than other trailing varieties.

Where Saphir Special delivers an intense, saturated cobalt-electric blue — bold and dramatic — Sky Blue offers a softer, cooler, more delicate pale blue that evokes clear summer skies. The white eye adds its characteristic bicolor sparkle without competing with the gentle tone of the flower. This makes Sky Blue one of the most widely compatible lobelia colors — light enough to harmonize with virtually any companion planting color, yet distinctive enough to register clearly in mixed basket and container compositions.

Regatta Sky Blue has been awarded the RHS Award of Garden Merit — one of the most respected garden plant recognitions in the world, given to plants that perform reliably and well under garden conditions. This recognition reflects the variety’s consistent performance, reliability, and high ornamental value across a range of conditions.

Regatta Sky Blue within the Regatta Collection — Color Positioning

The four Regatta varieties available in this collection form a complete, harmonious color palette for container and basket design. Regatta Rose provides warm carmine-rose. Regatta Blue Splash provides white with blue splashes — airy and painterly. Regatta Sky Blue provides soft pale sky-blue with white eye — delicate and celestial. Combined with Saphir Special’s intense electric blue, these four varieties cover the full spectrum from deep saturated blue through pale sky-blue, from white-splashed to warm rose — enabling diverse, professionally composed container combinations.

Plant Information

• Plant type: Tender annual (perennial in zones 10–11)
• Family: Campanulaceae
• Habit: Trailing, mounded, cascading
• Sun: Partial sun to partial shade — best performance in partial shade; full sun tolerated in cool conditions
• Soil: Moist, fertile, well-drained soil or container mix
• Water: Keep consistently moist — do not allow to dry out
• Spacing: 15–20 cm; multi-pelleted clumps naturally produce fuller containers

Seed Germination

• Seed depth: Surface sow; press lightly; do NOT cover — light aids germination
• Germination time: 15–21 days at 20–22°C
• Critical moisture: Maintain high moisture (saturated to medium-wet). seeds that dry out become hard — use plastic domes or regular misting throughout germination.
• Place seeds on surface of fine, moist, sterile seed-starting mix. Press lightly without covering.
• Maintain consistently high moisture from day one.
• Germination takes 15–21 days.
• Transplant in natural clumps of 3–5 seedlings per position.

Growing Tips

• All growing requirements are identical to Regatta Rose and Regatta Blue Splash.
• Start 8–10 weeks before desired transplanting date.
• Plant in partial shade location for best performance.
• Plant along with other cool season crops for best blooming.
• In Gulf conditions, a position with morning sun and afternoon shade protection is particularly beneficial for Sky Blue — the soft pale color can fade slightly in intense direct afternoon sun, while maintaining moist roots and partial shade preserves the celestial quality of the flower color at its best.
• Feed every two weeks — balanced fertilizer through early season, then switching to low-nitrogen formula to maximize bloom production. Keep consistently moist at all times.
• Sky Blue is particularly effective in mixed container combinations where its pale, delicate tone provides a light, airy element that prevents combinations from becoming visually heavy. It pairs especially beautifully with white flowers, silver foliage, soft pink, and lavender companions.

Gulf Planting Season

• Best sowing time in the Gulf: August–September (indoors)
• Transplanting: October–November
• Expected flowering: November–March (Regatta early-flowering advantage — 3–4 weeks before standard trailing varieties)
• Note: RHS Award of Garden Merit recognition reflects consistent, reliable performance. Partial shade placement in Gulf conditions preserves the pale sky-blue color quality at its best.

Garden and Container Uses

• Hanging baskets — soft celestial sky-blue cascades
• Window boxes and railing planters
• Mixed container combinations — light airy “spiller” that harmonizes with all companion colors
• Patio and balcony containers
• Border edging in cool-season beds
• Pollinator-friendly — attracts butterflies
