Winter

Winter deciduous trees.

Deciduous winter trees appear for all areas where the simulator depicts deciduous trees and the winter season applies. These trees show significantly less leaves and look great in winter landscapes with or without snow.

Tree canopy

Selectable deciduous tree canopy.

You can choose an irregular-shaped canopy instead of the default rounded one for deciduous trees. This design adds a unique touch, diversifying the shapes of these trees. It also increases color variation within the tree, enriching its overall appearance.

Tree height

Choose your tree height.

3 height options are available for trees: short, medium, and tall. Some trees in the app have been resized for more realistic proportions, including the large default trees seen in Sydney, Australia.
