The Blue Lobelia is a herbaceous perennial that exhibits impressive flower spikes covered in deep blue blossoms. Known as Lobelia Siphilitica, the Great Blue Lobelia, Great Lobelia, Cardinal Flower, and Blue Cardinal Flower, this plant is native to eastern and central Canada and the United States. It originates from the Campanulaceae family.
This showy perennial comprises stems that will reach 2 to 5 feet long and 10 to 18 inches in combined width. Each stem will have a series of bright green spearheaded leaves with serrated edges. This bellflower will bloom lavender-blue tubular flowers in the late summer months of July, August, September, and October. These tend to be crowded together at the uppermost part of the plant's stem. These elongated clusters produce a stark appearance that can contrast any garden.
Blue Lobelia is also known as Great Blue Lobelia
Each flower is parted into two bigger lips. The top lip is further segmented into two areas. The lower lip is segmented into three, which provides the perfect landing areas for heavy bumblebees. As they weigh down on the lower segment of the flower, this naturally opens up the flower's interior so the bee can easily reach its nectar. This provides an elongated capsule-like appearance. This stark perennial has a fibrous root system, which allows it to survive in various types of soils. It will attract hummingbirds, butterflies, and honeybees when in full bloom. Furthermore, this hardy plant is both rabbit and deer resistant.

This lovely flower is relatively simple to propagate and flourishes with or without sun. Its larger leaves allow it to soak up the sun in droves. When it blooms, elegant blue clusters form in the leaf's axils. This makes it the perfect plant for creating a calming blue color with a pleasant green background. This upright perennial will add vertical interest to any landscape design.
