Mandovila plant little white flowers

Lawrenceville, GA

I have two mandevillas planted in the ground. They survive the winter every year and have gotten huge! However instead of beautiful red big flowers it is covered in little tiny white fragrant flowers. Anyone know why? And can I ever get the red flowers back?

Pictures? Are they the same kind of flower?

Wow.....that looks an awful lot like Trachelospermum jasminoides, Confederate jasmine

The flower is smaller than a jasmine and when I planted it 4 years ago it had big red flowers. It flowered for two years then third and fourth year this is what I get. I never brought it in for wintering. It is planted in the ground and not in a pot. The leaves are healthy end I have to keep cutting it back because it wants to spread everywhere

Kshogs, I would recommend posting this on the PlantID Forum here on DG Sounds like more going on than a change in blooms...a possible graft and the grafted part died? Please do post there and add a close up of the flowers and also the stems and leaves.

The white flowers are NOT Mandevilla's, these are some form of Jasmine or other vine, IF you can reach under the bottom of the Manevilla, search carefully around the soil and you should feel the stems of the vine that has grown through the Mandevilla, either break the stems or try tug it out from the soil.
Remember all vines don't harm their host plants and it may not be this vine causing the Mandevilla to stop producing their beautiful Red Flowers, it might need a good feed to give nutrients, or it may require the crust to be raked from the top soil so water can penetrate way down to the roots, either way, you need to identify the vine as it might spread it's way all around your plants.
Best regards. WeeNel
