Allamanda

I'm pretty sure that's Allamanda 'Cherries Jubilee'. I have the same plant. It's a wonderful flowering woody vine or shrub!

Thanks for the name Delonix1

You're welcome.

I know Dipladenia, Mandevilla and Allamanda look so much a like. They're all in the same Apocynaceae family.

Is there a yellow Mandevilla? That part of the family grows in the bay area.

I know there's so many Mandevilla hybrids. I've seen dozens of hybrids for sale at Walter Andersen's Nursery here in San Diego.
