Gnaphalium unionis, commonly known as Jersey Cudweed or Union Cudweed, is a perennial herb native to the eastern United States, particularly thriving in dry, open areas such as fields, roadsides, and waste places. It typically grows at a moderate rate to a height of 0.5-2 feet (0.15-0.6 meters) and a width of 0.5-1 feet (0.15-0.3 meters). The plant has a rosette of basal leaves and erect stems with alternate leaves that are woolly and grayish-green. Its small, white, inconspicuous flowers bloom in clusters in the summer, and while not showy, they do attract a variety of pollinators.

Jersey Cudweed is valued for its drought tolerance and ability to thrive in poor soils, making it a suitable choice for xeriscaping and naturalistic plantings. It is also used in wildflower meadows and as a filler in borders due to its low maintenance requirements. In cultivation, it prefers full sun to part shade and does well in medium to fast-draining sandy or loam soils. It is a low-water plant, ideal for gardeners seeking to reduce irrigation needs. However, it can spread rapidly and may become weedy in some conditions, so it should be monitored to prevent unwanted spread.CC BY-SA 4.0
