When not in bloom, this plant remains attractive and often appears grasslike.

Garden tips: Narrowleaf silkgrass blooms later than many Florida native wildflowers. It is easy to establish and maintain in a garden setting. If grouped with other plants, it will typically contain itself; however, if planted alone in an open setting, an individual plant may slowly sucker and fill in the space. That said, narrowleaf silkgrass can be quite attractive en masse. Although it does not readily reseed itself, fresh seeds will germinate easily. Plants should be cut back after they have bloomed.
