Shrubs with flowers do not change color in different seasons

Describe the bug
Shrubs with flowers do not change color in different seasons, I understand this is no way to fix, so I propose to make it possible to remove these bushes from the world, so as not to spoil the visual picture, and as a variant, to make their return when the warm season and warm flowers.
