Creeper for ID : 300411 : AK-2: Again taken at the Flower Show at Jijamata Udyan, Mumbai in Feb,2011.
… could it be Allamanda ?
This could again be Mandevilla sp. or may be a hybrid!!
I thought so too initially but the leaves are different and the flower is very narrow at the base unlike as in Allamanda.
I came across a reply by … in another post suggesting ‘Alice Dupont’ Mandevilla.
My post could also be close to Mandevilla x amabilis ‘Alice du Pont’ or Mandevilla x amabilis, since the leaves are matching.
This is just a suggested id.
