Q.Are There Certain Varieties Of Mandevilla That Do Not Produce Seed Pods?
I have had mine a few years and it’s gets full sun and has lots of flowers the entire summer. It has never had seed pods and I am wondering which ones I should look for that do.

It is very easy to miss the seed pods. They can resemble twigs, or fat stems, or bean pods, and contain very small and hairy seeds. (They kind of remind me of milkweed or dandelion a bit.) Cutting off spent blooms will remove potential seed pods. Potassium can help with seed formation, but make sure that the soil does not have plenty, already.
