I would start by macro of crinum lily. Very fragrant and large blooms.
Murraya exotica is blooming profusely as monsoon has started here. No aroma can compete that of murraya's.
And when we talk of rains and monsoon, rain lilies come into mind and into bloom as well.
Allamanda is another climber growing right now. Many colors are available of this beautiful climber but the toughest one is the yellow one.
