Shimul (Shimul Phul/ful) is a leading spring flower of Bangladesh. It blooms in spring season and it is an unique feature of this tree is that there are no more leaves during it's time of blooming. It's dark reddish petal covering with dark green calyx really gives glorious view. This gorgeous flower is only seen in the South Asia, specially in Bangladesh(Though I don't know clearly). Shimul flower leads as great to spring when a sound much flowers are to be bloomed.
