They are really beautiful. Usually after the buds appear it takes a very long time to bloom. In a way good! The hope to see it bloom lasts for a long time & the feel is deeper & a prolonged one. And similarly once it blooms, it lasts for a couple of days.
'Nandi Battalu' that I know are also beautiful but do not smell good. I know of two types. One which is slender & small and the other which has multiple petals which I've seen in Mangalore. This time when I had been to M'lore, I had photographed the multiple petaled NandiBattalu.
Whateva they are called, they are still beautiful. Their white & off white colors and the twisted petals make them so different.
