Syngenta describes this selection as a bright picotee color mix, with strong branching for packs, small pots and bedding.

[Syngenta Flowers selection page](https://www.syngentaflowers.com/emea/product/flower/70020243). Petunias are half-hardy annuals for seasonal color. Illinois Extension recommends full sun and moist, well-drained soil, and notes that heavy soil can reduce flowering. Use a pot with drainage or a free-draining bed, and keep the soil moist without leaving roots waterlogged.

Remove tired growth as needed and keep the soil evenly moist with good drainage.
