For urban gardeners, understanding the sun exposure for flowering plants in planter boxes is key to a vibrant display. Most flowering plants require a minimum of 6 hours of direct sunlight daily to bloom profusely. This is often labeled as "full sun." However, the urban environment creates unique conditions. Assess your space by observing light patterns over a full day. South-facing balconies typically get the most intense light, ideal for sun-lovers like petunias and geraniums. East or west-facing locations offer partial sun (4-6 hours), suitable for plants like begonias or impatiens. North-facing spots with less than 3 hours of direct light require shade-tolerant blooms such as coleus or fuschia. Remember, reflected heat from walls can intensify sunlight, while tall buildings may cast long shadows. Always match the plant's needs to your specific microclimate for a thriving urban flower garden.
