Identifying a Low Spreading Purple Flower from a Hanging Basket

A low, spreading plant with fern-like leaves and brilliant purple flowers just above the foliage is likely Verbena. Verbena flowers form round clusters of small blooms. It's an annual in most climates but may overwinter where winters stay above 45°F.

If it's not verbena, consider Scaevola (fan flower) or Portulaca (moss rose), though their foliage differs. Take a photo to a local nursery for confirmation. Enjoy the volunteer—it's a tough, colorful groundcover.
