These are open-pollinated African lobelias bred specifically for compact, mounded growth and a spectacular color range. The Regatta Series combines early flowering speed (77-84 days from seed to maturity depending on conditions) with the fragrant intensity that makes lobelia special, creating dense mounds that work as well in containers as they do at the front of flower borders. The range of unique signature colors means you can build cohesive plantings or mix for complex, layered effects.
Regatta Series Lobelia is grown as an ornamental annual flower for containers, hanging baskets, window boxes, and garden beds. The compact, mounded habit and prolific blooming make it particularly valued for edging borders, filling spaces in mixed containers, and creating colorful displays on patios and in small gardens.

Start seeds indoors 6-8 weeks before your last spring frost. Lobelia seeds are very fine; sow them on the surface of moist seed-starting mix without covering, as they need light to germinate. Keep soil temperature around 70°F and maintain consistent moisture. Seedlings will emerge in 10-14 days. Provide bright light (grow lights work well) once germinated.
Transplant seedlings outdoors after your last frost date when soil has warmed. Harden off plants gradually over 7-10 days by exposing them to outdoor conditions in increasing increments. Space transplants 6 inches apart. Lobelia establishes quickly and will begin flowering within weeks of transplanting.
Direct sowing is not recommended due to the extremely fine seed; indoor starting gives much more reliable results.
Regatta Series Lobelia's naturally bushy, mounded habit requires minimal pruning. Pinch back seedlings when 2-3 inches tall to encourage branching and a fuller shape. Deadhead spent flowers regularly to maintain continuous blooming throughout the season, though this compact cultivar tends to flower prolifically without deadheading.
