TriTunia™ Mix Petunia

TriTunia™ Mix is a upright grandiflora petunia with a mixed flower color selection. Syngenta lists 30–35 centimeters in both height and width, flowering from mid-spring through summer, and identifies this selection in the TriTunia series ([Syngenta’s exact product page](https://www.syngentaflowers.com/emea/product/flower/70065675)). ## Site and display Grow in sun in a seasonal bed or container. Its upright form offers a different outline from the mounding TriTunia colors; the metric dimensions convert to about 12–14 inches each way. Combine it with contrasting foliage or complementary annual flowers. ## Seasonal role Syngenta describes TriTunia as a vigorous grandiflora range selected for early flowering and relatively uniform timing. The Mix name identifies a mixture rather than one flower color. ## Maintenance Check container moisture often during warm weather. Water the root zone when the mix begins to dry and allow excess to drain; RHS research using petunias found measured regular watering supported good growth without requiring pots to drip after watering ([RHS container-watering research](https://www.rhs.org.uk/science/gardening-in-a-changing-world/water-use-in-gardens/watering-containers)).
