Gardeners' Notes:

Despite the fact this native is well-adapted to xeric conditions, Narrow-leaf Silkgrass thrived and multiplied in my garden throughout the wettest year in 110 years. My soil is silty sand and the water table has been only inches below the surface at times this summer. It outcompeted weeds like dollar weed and Florida betony with little or no assistance on my part and is currently standing over 2' tall in full bloom.

I think it deserves to be used more often in the hot and humid lower South.

Golden Aster occurs in dry habitats throughout the southeastern US. It is encountered commonly in Florida scrub. Golden aster is a herbaceous perennial reaching about 2' high. The leaves look like silvery grass blades and both the stem and leaves are covered with silky hairs. The numerous flowers, appearing in summer and autumn, are about an inch across. Golden aster makes an excellent addition to perennial borders and natural areas. Once established it is maintenance-free. It needs light, sandy soil and full sun.
