Wonderful plant whose name I do not know

Could it be Chinese Jasmine?

I thoght it might be trachelospermum jasminoides, the star jasmine, but that is sweetly scented. so is solanum jasminoides, the potato vine, but not so strongly.

When the latin name of a plant ends in "something-oides" I think it means that it is not a variety of the "something", but is similar to it. ( just as an ovoid is almost an oval egg-shape, but not exactly one) I may be wrong.

Try taking a photo of it using Google lens. I find this a good way to identify plants.

I have done some more research and I think it is Pandorea jasminoides ‘Lady Di’.

I can thoroughly recommend it - it is truly wonderful.

Sounds like jasmine to me, too. I have one like that and another one with larger pink flowers. They grow like Topsy here.

Insufficient sunlight can cause the normally highly perfumed trachelospermum jasminoides to have little or no scent so perhaps that is the answer? it certainly sounds like star or confederate jasmine.
