Summary

Trichostema dichotomum, commonly known as Forked Bluecurls, is an annual herb native to open woodlands, grasslands, and fields in the Eastern United States. It typically grows to a height of 1-3 feet (0.3-0.9 meters) and is characterized by its square, erect, hairy stems and opposite, simple leaves. The plant produces distinctive blue flowers with curled stamens that bloom in late summer, adding a splash of color to the landscape. The flowers are quite showy and attract pollinators such as bees and butterflies.

Forked Bluecurls is appreciated for its unique flower structure and the ease of growing it from seed, making it a charming addition to wildflower gardens, meadows, and naturalized areas. It thrives in full sun but can tolerate partial shade and prefers well-drained soils. Gardeners often use it for its ornamental value and to support native pollinators. However, it can be short-lived and may need to be reseeded annually to maintain a presence in the garden.CC BY-SA 4.0
