Firefly Blue Lobelia

Firefly Blue Lobelia (Lobelia 'Firefly Blue', syn. 'Weslofiblu') is a charming, prolific trailing annual smothered in vivid blue flowers with crisp white accents that create a delicate, two-tone sparkle effect reminiscent of fireflies dancing across a midsummer garden. This vigorous, well-branched variety delivers an extraordinary abundance of tiny, intricate blooms that cascade beautifully from containers, hanging baskets, and window boxes — creating a soft, airy, blue-and-white display that pairs harmoniously with virtually any companion plant color palette throughout the cool growing season.

Grown from our premium organic heritage program, each plant ships with a Professional Grade root system — dense, well-branched, and ready for immediate establishment. Firefly Blue thrives in full sun to part shade with consistent moisture, performing most prolifically during the cool temperatures of spring and fall while maintaining reasonable bloom production through summer with adequate moisture and protection from intense afternoon heat. Its trailing, cascading habit makes it an outstanding spiller in mixed container arrangements, a graceful edge plant in raised beds, and a classic companion for white alyssum, pink petunias, and warm-toned summer annuals throughout the season.

• Vivid Blue & White Bicolor Blooms — Intense blue flowers with crisp white accents create a delicate two-tone sparkle effect that adds a cool, airy quality to mixed containers, hanging baskets, and garden border edges throughout the season.
• Prolific Extended Bloom Production — Produces an extraordinary abundance of tiny, intricate blooms continuously throughout the cool-season growing period, delivering a reliable carpet of blue-and-white color with minimal maintenance.
• Graceful Trailing Spiller Habit — Naturally cascading, trailing form is outstanding as a spiller in mixed container arrangements, hanging baskets, window boxes, and raised bed edges where flowing, airy color is desired.
• Outstanding Cool-Season Performer — Blooms most prolifically in the moderate temperatures of spring and fall, making Firefly Blue an essential plant for extending the container garden color season beautifully into shoulder seasons.
• Versatile Companion Plant — Cool blue-and-white tones complement virtually every companion plant color palette — equally stunning with warm orange and yellow annuals as with soft pink and white cool-tone container designs.

These 4" healthy live plants thrive in full sun to part shade with consistent, even moisture — water regularly to keep soil evenly moist and apply a balanced liquid fertilizer every two weeks to sustain prolific blooming. Firefly Blue Lobelia is a cool-season annual; plant after last frost for spring and early summer color, or plant in late summer for a vibrant fall display. Trim lightly after the main bloom flush to encourage a fresh second wave of flowers through the season.
