Tree Seaside Tansy

Borrichia arborescens, commonly known as Tree Seaside Tansy, is a perennial species native to the coastal regions of the southeastern United States, particularly in salt marshes and sandy soils. This plant typically grows to a height of 3 to 6 feet, exhibiting a bushy form with a woody base and numerous upright stems. Its leaves are thick, succulent, and lanceolate, providing a striking contrast to the bright yellow, daisy-like flowers that bloom from late summer to fall. The flowers are an important nectar source for various pollinators, while the seeds are dispersed by wind and water, aiding in its colonization of disturbed coastal areas.

Ecologically, Borrichia arborescens plays a vital role in stabilizing sandy soils and providing habitat for wildlife. It is well-adapted to saline environments, exhibiting salt tolerance that allows it to thrive in conditions where many other plants cannot. Human uses of this species include its application in coastal restoration projects, where it is utilized to combat erosion and enhance biodiversity. Its resilience to harsh coastal conditions makes it a valuable addition to gardens aimed at attracting pollinators and supporting local ecosystems.
