Starship™ Blue Lobelia

Starship™ Blue cardinal flower is a tall, upright lobelia selected for blue flowers and green foliage. PanAmerican Seed describes this variety as 24–28 inches tall, taller than the rest of the Starship series, and lists summer-to-autumn flowering for the series. ## Garden use The [PanAmerican Seed plant page](https://www.panamseed.com/Products/039402933000616/lobelia-starship-blue/) lists hardiness in USDA zones 6a–10b, sun exposure, and an 8–12-inch width. It is suited to beds, borders, and mixed annual or perennial containers; the breeder notes that the flowers attract hummingbirds and butterflies. The cultivar-specific height note is 24–28 inches, while the page’s general plant-information table gives 20–24 inches for the series, so expect some variation with growing conditions and the measurement context. ## Maintenance Provide sun and consistent moisture, especially during warm weather; PanAmerican notes that the series prefers higher temperatures, humidity, and moisture. Use a container with drainage when growing it in a mixed planting, and allow room for its upright flower stems above neighboring plants.
