TriTunia™ ProFormula Mix Petunia

TriTunia ProFormula Mix is Syngenta’s multicolor, large-flowered annual petunia selection in the TriTunia series. The official product page lists a mounding habit, a garden size of 10–12 inches tall by 12–14 inches wide, and flowering from mid-spring through summer. The series is described as vigorous and uniform in flowering, with early flowering under short, dark days; this mix is suited to packs and pots. [Syngenta’s ProFormula Mix page](https://www.syngentaflowers.com/ams/product/flower/70067443). ## Growing Grow in full sun to part shade and moist, well-drained soil. For established petunias, UF/IFAS recommends deeper watering rather than frequent light watering; adjust for rainfall and how quickly containers dry.
