Cyclic form of nature

Four pictures are from same area. The first is taken from a distance compare to other three. The first was also taken during winter so you do not see flowers in the garden and leaves in the big tree. The second is during spring season and plants are developing fast. Third and fourth are at the stage of flowering (same place taken from opposite directions). Flowers are of same season but in two shifts. After the tulips, marigolds were seen. Marigolds remind me of Dashain and Tihar in Nepal.
