The initiation of flowering in petunias is governed by a strict set of environmental cues, with temperature and day length being paramount. Petunias are tender perennials, but in most temperate climates, they are grown as annuals because they cannot survive freezing temperatures. As winter recedes and soil temperatures reliably climb above 60°F (15°C), the plants shift from vegetative growth to reproductive mode. While many modern cultivars are considered "day-neutral" and will flower regardless of day length, their ancestors are long-day plants, meaning they require increasing hours of sunlight to trigger bud formation. Consequently, the explosive bloom period aligns with the long, bright days of June and July. For this reason, gardeners who plant petunias too early—while nights are still cold—will be rewarded with stunted growth and a frustrating delay in flowering. when do petunias flower
