Hi there! I have this flowering plant which was given up by my neighbor, and is now happily thriving in our garden, can someone ID it please? Took this photo today, as I saw her finally opening up one of her many buds..

Without seeing the whole plant, it appears to be a Mandevilla (formerly called Dipladenia).

Looks like a Dipladenia.

Oops, cross-posted with you Carol. Yes, Dipladenia or Mandevilla, I think.

Thanks for the ID! I took a photo again, this time of the whole plant..and doing an internet search based on the ID's you all gave, it does look like a Dipladenia..but since it is vining..it is more a mandevilla...thanks a lot for all your help!

Could be this one.. Mandevilla sanderi 'Sun Parasol Crimson'. Is it more red than shows? Cameras often don't show reds well.
