The flowers are produced in panicles (sometimes solitary), and have a five-lobed corolla, typically large (2–5 cm or more long), mostly blue to purple, sometimes white or pink. Below the corolla, 5 leaf-like sepals form the calyx. Some species have a small additional leaf-like growth termed an "appendage" between each sepal, and the presence ...

[5] The flowers have six tepals and six stamens, and are arranged singly or in racemes of two or three. Petals may be reflexed ...
The flowers are more closely clustered towards the top of the raceme and become more infrequent further down with the lower flowers begin blooming first. [6] Great lobelia flowers are notably larger than many other lobelia species. Flowers are typically blue or violet, but can be lighter, even white and are usually about 1 in (25 mm) long. [8]
The flowers are arranged in a racemose inflorescence of extremely long-lasting blooms. These attractive bell-shaped flowers are short-stalked, large and hermaphroditic, with different shades of violet-blue or rarely white. The corolla has five fused petals with lightly bent lobes (known as a coronate flower type).
Growing to 60 cm (24 in) tall by 30 cm (12 in) wide, it is an herbaceous perennial with dark green leaves and blue flowers in late summer.
