Many modern homes allow for plenty of light from outside. Rooms facing the afternoon sun will admit a lot of heat through the windows and many Bonsai species will suffer in these conditions. They should be kept away from direct sun but still be exposed to enough light.
Do not keep Bonsai trees on the windowsill because a dramatic temperature change occurs during day and night time close to the glass, especially during winter. These constant extreme temperature fluctuations can be fatal to tropical and subtropical Bonsai species.
By positioning your Bonsai trees away from these extreme conditions and reducing the strength of the sunlight a much wider variety of Bonsai species can be grown successfully.
Indoor Bonsai species that is suitable for bright sunny rooms:
Chinese Yew
Prodocarpus
Bamboo
Bougainvillea
Chinese Elm
Jasmine Orange
Lagerstroemia
Olive
Pistachio
Pomegranate
Privet
Serrissa
