(Ruellia humilis)

Wild petunia, also known as Fringeleaf wild petunia, Low wild petunia

This herbaceous perennial is known for its trumpet-shaped flowers and low-growing foliage. Optimal pruning times for wild petunia are spring through fall. Deadheading promotes further blooming and maintaining the plant's shape. Cutting back after its first flowering encourages a second bloom. Season-end pruning prepares it for winter, resulting in a denser growth the following season. Pruning benefits include healthier plants, more flowers, and control over size and spread.

Pruning in Spring allows gardeners to remove any winter damage and promotes healthy new growth as the wild petunia begins its active growing season. Early Summer trimming of spent flowers can encourage a second blooming and improve the plant’s appearance. Fall pruning is ideal for shaping the wild petunia, thinning out densely grown areas, and removing any dead or diseased foliage, which can improve air circulation and plant health overall.
