Hello to all, I am trying to find a name for the flowers in the attached photo. When I was in India they were grown in many places and used in many garlands. I have found very few images of them in garlands on the internet but really would like to know the name so I can source seeds and grow them.

In the photo, towards the right, the flowers are a very vivid deep pinky purple, with a papery texture that is dry on the growing plant and stays that way when plucked. They keep their colour when dried.

I have looked through traditional Hindu flowers in literature and popular flowers in India plus garlands resources and I can’t pin down a name.

Any help most appreciated. Thank you.
