The other names for this plant are Blue False Indigo, and Blue Wild Indigo. The scientific name is Baptisia australis. It grows to between 3 and 4 feet tall, and flowers in late May or June, depending on location. The plant can spread up to 4 feet, so give it plenty of leg room.
The flowers are striking in bouquets. The flowers give way to a seed pod, which produces a blue dye. The seed pods can make a great addition to dried floral arrangements.
You can find Blue Wild Indigo in most of the Eastern half of the United States, from Vermont, to Texas. They make a great addition to any native plant garden, or cottage garden in this part of the US. It is a perennial in zones 3-9, which means it will return year after year. New plants can be started from seed, but I have heard it can be a difficult process.
Blue Indigo is supposed to repel flies, but is a natural butterfly attraction, so a great addition to the butterfly garden.
These plants are also found in Native American medicine. They are supposed to remedy vomiting, toothaches, and coughing, as just a partial list of the many things this plant is listed as a help for.
This beautiful plant is definitely on my favorites list.
