Summary

Calibrachoa parviflora, commonly known as Seaside Petunia, is a perennial herb that is native to open woodlands and grasslands in southeastern South America, Mexico, and the southwestern United States. It typically forms a low-growing mat with slender, branching stems that creep along the ground and root at nodes. The upright branches bear fleshy, glandular leaves. Small, trumpet-shaped purple flowers bloom in the leaf axils, adding a splash of color to the plant’s appearance. Seaside Petunia flowers throughout the warm season, with a peak in spring and summer.

Seaside Petunia is valued for its ability to spread and fill in areas as ground cover, making it suitable for rock gardens, borders, and containers. It thrives in full sun to part shade and prefers well-drained soils. While it is drought-tolerant once established, regular watering will promote more vigorous growth and flowering. This plant is relatively low maintenance but can benefit from occasional trimming to encourage bushiness. It is not known for significant pest or disease issues, but it can become invasive in some regions, so gardeners should monitor its spread.CC BY-SA 4.0
