This will be hydrangea macrophylla. This is the most difficult one to manage to keep flowering, as most areas get slightly too cold for the old growth to survive. This only flowers on old growth, so if no old growth makes it, then there will be no flowers.

Now with the trumpet vine... It is likely a lack of fertilization. This article will help: https://www.gardeningknowhow.com/ornamental/vines/trumpet-vine/growing-trumpet-vines.htm
