Why the Audubon® Great Blue Lobelia?

Most of our woodland wildflowers bloom in spring, taking advantage of the warmer temperatures and the sunlight shining through the bare branches of the trees. When summer comes, they go dormant and retreat underground. This means that shady native spaces are typically not very colorful when the weather gets hot. What a pleasure it is, then, to see Great Blue Lobelia blooming away in late summer! Its periwinkle-blue blossoms bring a feeling of freshness to the garden. They bring hummingbirds, too! The Ruby-throated wonders will be frequent visitors during this stellar Spirit’s long bloom time.

Great Blue Lobelia grows in wet but well-drained soil in open woods over much of the eastern U.S. It is most abundant in the Midwest, but its range extends west to Colorado, south to Louisiana, and east to Massachusetts. This humble wildflower has been hailed as a supposed cure to many diseases over the years, the most famous being syphilis. In the 1700s, European settlers learned of the Iroquois using the plant to treat syphilis. Intrigued, they sent it to Europe for study, though scientists could find no proof of its effectiveness. Nevertheless, it was given a botanical name that would forever allude to the story. Among botanists, Great Blue Lobelia is known as Lobelia siphilitica.

How to use in the landscape?

Besides Hummingbirds, Great Blue Lobelia also attracts bumblebees to pollinate its flowers. These and other long-tongued bees are able to reach into the deep flowers for the nectar. Butterflies enjoy the blossoms, too. Monarchs and Swallowtails are special fans.

What is the definition of Native?

“In the United States, a native plant is defined as one that was naturally found in a particular area before European colonization. Native plants are the foundation of a region’s biodiversity, providing essential food sources and shelter for birds, especially those threatened by the changing climate. Since native plants are adapted to local precipitation and soil conditions, they generally require less upkeep, therefore helping the environment and saving you time, water, and money.” – The National Audubon Society

How To Plant

Steady moisture with good drainage is key with Great Blue Lobelia. It does not take kindly to drying out. Mulch well, preferably with compost or leaf mold, to keep the roots cool and moist. Protection from the hot afternoon sun is also important, especially in warm climates. In cool northern regions, full sun may be an option. Great Blue Lobelia is not a long-lived Spirit, but plants reseed when happy, so provide the right conditions, and the planting will endure indefinitely. Cut plants back any time after they have cast their seed and before new growth resumes in the spring.

How To Fertilize

Incorporate Elements Starter Plant food granular form into the soil when planting. If planting in spring or summer, start fertilizing late fall using Elements Starter Plant food granular form on an annual basis each late fall. Continue this for the first three years to get your plant well established.
