Summary
Trichostema brachiatum, commonly known as False Pennyroyal, is an annual herb native to open woodlands, grasslands, and fields. It is found in Central and Eastern USA and Southeastern Canada. This plant typically grows to a height of 1-2 feet (0.3-0.6 meters) and a width of 0.3-0.5 feet (0.09-0.2 meters). The False Pennyroyal has a bushy form and produces small, tubular flowers that are a distinctive combination of pink and blue, blooming in late summer to early fall. The flowers are arranged in loose clusters and are attractive to bees and butterflies, adding to the ecological value of the plant.
In cultivation, False Pennyroyal is appreciated for its aromatic foliage, which when crushed releases a minty fragrance, and its delicate flowers that add a splash of color to the garden. It is often used in wildflower gardens, as a border plant, or in naturalized areas. This herb prefers full sun but can tolerate light shade and requires low amounts of water, making it suitable for xeriscaping. It thrives in well-drained soils and is relatively low-maintenance, needing minimal care once established. However, it can self-seed prolifically under favorable conditions, which gardeners should consider when planting.CC BY-SA 4.0
