Fragrant flower

Question

When I was young , my granny had some flowers. They close up during daytime. Only open at night..and they are so fragrant. They are small , deep red colour, with small plants I was hoping to find out the name and buy the seeds.

Answer 1

I really need much more information to make an accurate guess, but one flower does come to mind with this description... Ornamental tobacco. It is extremely fragrant, with long thin flowers that can be almost any color.

Does this resemble the plant?
