Isotoma fluviatilis ‘White’
A white-flowered form of blue star creeper, this low mat-forming perennial spreads by creeping stems to one to three inches tall, knitting into a dense green carpet. It grows in full sun to part shade with regular, consistent water and stays low and walkable once established. From spring into summer it is dotted with small star-shaped white flowers, making it well suited as a lawn substitute, a filler between stepping stones and pavers, and a soft edging for paths and borders.
