What is the difference in indoor and outdoor azaleas?

Indoor azaleas are typically smaller, more compact varieties bred for pot cultivation, and they thrive in controlled environments with consistent humidity and temperature. In contrast, outdoor azaleas are larger, hardier varieties that can withstand varying weather conditions and are often planted in gardens or landscapes. Outdoor azaleas generally require more sunlight and have a longer blooming period compared to their indoor counterparts. Additionally, indoor azaleas may need more frequent watering and care due to their limited soil volume.
