([RHS botanical profile](https://www.rhs.org.uk/plants/292020/petunia-%C3%97-hybrida/details); [2026 Plug Connection program](https://www.germaniaseed.com/orderforms/2026/PlugConnection_784_2026.pdf)) ## Site and seasonal display Illinois Extension describes hybrid petunias as half-hardy annuals for full sun and moist, well-drained soil. Its overview covers a broad range of habits and flower colors, so use the plant’s own label and observed growth to plan spacing rather than assuming a size from another petunia. The RHS genus profile notes that petunias can be annuals or perennials and that flower timing varies with growing conditions.

In containers, check moisture regularly and adjust watering to heat, wind, and pot size; the RHS container study includes petunias among the plants assessed. Pinching later in the season can help petunias stay compact and continue flowering.
