Thread-leaf evening primrose is a delicate annual wildflower with narrow, thread-like foliage and small yellow flowers that open in the evening. This compact plant blooms from June through September and thrives in sunny, dry conditions with minimal care.
In an HOA neighborhood

Works well in: backyard only.
