Q.low growing flowering plants
I have a small flat where I want to keep flowering, good smelling plants indoors or outside. They should grow at low height and width. Any suggestions?

When you say "low growing" what maximum height is desirable to you?
I am going to refer you to this website called "flowers of india" which has beautiful photo galleries along with height and width specifications for each flower featured. Also, the flowers featured on this site will be sure to thrive in your location. This link will take you directly to the fragrant flowers section of their website:
