Distort geometry against surface?

I am trying to model some terrarium type designs that have plants and vegetation pressed up against a vertical glass surface. So far distorting/scaling/modifying 3D plant models on my own isn’t achieving the desired effect, let alone taking up a lot of time.
Does anyone know any plugins or tricks that could help achieve this effect?

Can you post a screenshot of what your model looks like and/or a reference image of the look you’re trying to achieve?
