Summary
Rostellularia procumbens, commonly known as Spreading Ammannia, is an evergreen herb native to wetlands, moist woodlands, and riparian zones across Southeast and East Asia. It exhibits a moderate growth rate, reaching heights and widths of 1-1.5 feet (0.3-0.5 meters). This plant features small, tubular flowers that are typically purple or white and are considered showy due to their abundance. These flowers bloom in the summer and spring, attracting pollinators. Spreading Ammannia has a sprawling habit and can form dense mats of foliage.
Spreading Ammannia is valued for its vibrant flowers and ability to thrive in wet conditions, making it suitable for water gardens, rain gardens, and as a ground cover in moist areas of the landscape. It is adaptable to a range of soil types, including clay, loam, or sandy soils, but requires consistent moisture to flourish. While it prefers full sun or part shade, it is tolerant of a variety of light conditions. Gardeners should be aware that in some regions, it can become invasive due to its rapid spreading capability.CC BY-SA 4.0
