Typical Landscape Use
Establishment and Care Instructions
Full sun, hot dry conditions may seem harsh for this little plant, but it is tough! Part shade is tolerated, with reduced flowering. Try growing in a dry spot with afternoon sun and morning shade-*a 'different' situation for many other plants. Due to its size, be careful of exuberant neighbors, Wild Petunia can be easily overcome by larger neighbors.

Basic Description

A native perennial of great character with flowers that will remind you of the annual bedding plant Petunia. Charming, low growing clumps produce light purple/lavender, tubular flowers from May to Oct. The flowers arise in groups at the leaf axis. The square stems and the leaves are both quite hairy—a natural defense against dry conditions.
